You can use `theme_get()` to display the possible options for theme. 
You can control the legend font size using:

    + theme(legend.text=element_text(size=X))

replacing X with the desired size.

    theme(plot.title = element_text(size = 12, face = &quot;bold&quot;),
        legend.title=element_text(size=10), 
        legend.text=element_text(size=9))



You can also specify the font size *relative* to the `base_size` included in themes such as `theme_bw()` (where `base_size` is 11) using the `rel()` function.

For example:

    ggplot(mtcars, aes(disp, mpg, col=as.factor(cyl))) +
      geom_point() +
      theme_bw() +
      theme(legend.text=element_text(size=rel(0.5)))

A simpler but equally effective option would be:

    + theme_bw(base_size=X)

I am getting into the Entity Framework, but I am unsure if I am missing a critical point in the code-first approach.

I am using a generic repository pattern based on the code from https://genericunitofworkandrepositories.codeplex.com/ and have created my entities.

But when I try to access or modify the entity I run into the following:

&gt; System.InvalidOperationException: The entity type Estate is not part
&gt; of the model for the current context.

It happens when I am trying to access it from my repository:

    public virtual void Insert(TEntity entity)
    {
        ((IObjectState)entity).ObjectState = ObjectState.Added;
        _dbSet.Attach(entity); // &lt;-- The error occurs here
        _context.SyncObjectState(entity);
    }

The database (./SQLEXPRESS) is created just fine, but the entities (tables) is just not created on startup. 

I am wondering if I need to explicit set the mapping of the entities? Is EF not able to this by its own? 

My Entity is:

    public class Estate : EntityBase
    {
        public int EstateId { get; set; }
        public string Name { get; set; }
    } 


My context is as so:

    public partial class DimensionWebDbContext : DbContextBase // DbContextBase inherits DbContext
    {
        public DimensionWebDbContext() :
            base(&quot;DimensionWebContext&quot;)
        {
            Database.SetInitializer&lt;DimensionWebDbContext&gt;(new CreateDatabaseIfNotExists&lt;DimensionWebDbContext&gt;());
            Configuration.ProxyCreationEnabled = false;
        }
    
        public new IDbSet&lt;T&gt; Set&lt;T&gt;() where T : class
        {
            return base.Set&lt;T&gt;();
        }
        
    }



Is there any specific reason why this error occurs? I have tried enable migrations and enable automatic migrations without any help either.

I have a list of words:

    bau
    ceu
    diu
    fou
    gau

I want to turn that list into:

    byau
    cyeu
    dyiu
    fyou
    gyau

I unsuccessfully tried the command:

    :%s/(\w)(\w\w)/\1y\2/g

Given that this doesn&#39;t work, what do I have to change to make the regex capture groups work in Vim?

Is there a way to increase the font size in `ggplot2`? I think I need to specify something like `legend.key.width = unit(2, &quot;line&quot;)` in the `theme` function, but that is used to adjust the keys in legends, not the font sizes. Thanks!

<p>Is there a way to increase the font size in <code>ggplot2</code>? I think I need to specify something like <code>legend.key.width = unit(2, "line")</code> in the <code>theme</code> function, but that is used to adjust the keys in legends, not the font sizes. Thanks!</p>


I have thousands of points in one figure and set `size = 1`. However, the point size in the legend is reduced too. How to increase the point size in the legend?

For example.

    num &lt;- 10000
    set.seed(1)
    df &lt;- data.frame(x = seq(1, num), y = runif(num), z = rep(1:2, each = num / 2))
    df$z &lt;- factor(df$z)
    library(ggplot2)
    p &lt;- ggplot(df, aes(x, y, colour = z)) + geom_point(size = 1)
    p

How to increase the size of points in legend of ggplot2?

Let&#39;s say I have a list like this:

    x = list(list(1,2), list(3,4), list(5,6))

I would like a list that contains only the first elements of the nested list. I can do this by returning another list like so

    x1 = lapply(x, function(l) l[[1]])

Is there shortcut notation for this?

I&#39;m trying to install R using Homebrew. I ran these commands which are recommended elsewhere on SO:

    brew tap homebrew/science
    brew install R

For `brew tap homebrew/science`, I&#39;m receiving this error:

    Error: Already tapped!

For the second command, I receive this:

    Error: No available formula for r 

Any suggestions?

I&#39;ve been reading the `ggplot2` documentation for both functions. I was wondering what were the differences and what would be right situation for using each function (`facet_wrap()` and `facet_grid()`). 

    library(ggplot2)

    p &lt;- qplot(displ, hwy, data = mpg)
    p + facet_wrap(~ cyl)
    
    p + facet_grid(~ cyl)

I provide this small example to serve as starting point. The difference seems to be wrap makes the plots more autonomous and grid makes one plot all together.


What&#39;s the difference between facet_wrap() and facet_grid() in ggplot2?

**Edit:** This question has been marked as duplicated, but the responses [here][1] have been tried and did not work because the case in question is a line chart, not a bar chart. Applying those methods produces a chart with 5 lines, 1 for each year - not useful. Did anyone who voted to mark as duplicate actually try those approaches on the sample dataset supplied with this question? If so please post as an answer.

**Original Question:**

There&#39;s a feature in Excel pivot charts which allows multilevel categorical axes.I&#39;m trying to find a way to do the same thing with `ggplot` (or any other plotting package in R).

Consider the following dataset:

    set.seed(1)
    df=data.frame(year=rep(2009:2013,each=4),
                  quarter=rep(c(&quot;Q1&quot;,&quot;Q2&quot;,&quot;Q3&quot;,&quot;Q4&quot;),5),
                  sales=40:59+rnorm(20,sd=5))

If this is imported to an Excel pivot table, it is straightforward to create the following chart:

![][2]

Note how the x-axis has two levels, one for quarter and one for the grouping variable, year. Are multilevel axes possible with `ggplot`?

NB: There is a hack with facets that produces something similar, but this is not what I&#39;m looking for.

    library(ggplot2)
    ggplot(df) +
      geom_line(aes(x=quarter,y=sales,group=year))+
      facet_grid(.~year,scales=&quot;free&quot;)

By using R, is it possible to place 2 ggplot together (i.e., on the same plot)? I wish to show a trend from 2 different data frames and instead of putting them one next to the other, I&#39;d like to integrate them together in one plot and only to change the color of one of them (the black dot).

To be more specific, I have the following 2 visuals:

    ggplot(visual1, aes(ISSUE_DATE,COUNTED)) + geom_point() + geom_smooth(fill=&quot;blue&quot;, colour=&quot;darkblue&quot;, size=1)

and

    ggplot(visual2, aes(ISSUE_DATE,COUNTED)) + geom_point() + geom_smooth(fill=&quot;red&quot;, colour=&quot;red&quot;, size=1)

They look like this (both have black dots and I&#39;ll need to change one of them to something different):

How to combine 2 plots (ggplot) into one plot?

I would like to automatically wrap my labels in ggplot2, i.e. insert line breaks of long labels. [Here][1] is written how to write a function (1) for it, but sadly I do not know where to put `labeller=label_wrap` in my code (2).

(1) function by hadley

    label_wrap &lt;- function(variable, value) {
      lapply(strwrap(as.character(value), width=25, simplify=FALSE), 
             paste, collapse=&quot;\n&quot;)
    }

    
(2) code example

    df = data.frame(x = c(&quot;label&quot;, &quot;long label&quot;, &quot;very, very long label&quot;), 
                    y = c(10, 15, 20))

    ggplot(df, aes(x, y)) + geom_bar(stat=&quot;identity&quot;)
[![Histogram with long label not wrapped][2]][2]

I&#39;d like to wrap some of the longer labels here.
