Issues using ggplot2 aes_string with box plots

[Egor]

I seem to be having problems using ggplot2. I get the following error while

Error: stat_boxplot requires the following missing aesthetics: x, y

Here is an example:

x='group'
y='value'
df=data.frame(group=c('A','A','B','B','C','C'),value=c(1,2,3,4,5,6))
ggplot(data=df,aes_string(x,y)) + geom_boxplot() #returns the error
ggplot(data=df,aes(x,y)) + geom_boxplot() #plots nonsense (naturally)
ggplot(data=df,aes(group,value)) + geom_boxplot() #works, but not strings


Any suggestions on how I can make this work with strings?

Hi Egor,

Try:

ggplot(data=df,aes(x=group,y=value)) + geom_boxplot()?

Cheers,
Albert

This should work:

x='group'
y='value'
df=data.frame(group=c('A','A','B','B','C','C'),value=c(1,2,3,4,5,6))
ggplot(data=df,aes_string(x=x, y=y)) + geom_boxplot()

x='group'
y='value'
df=data.frame(group=c('A','A','B','B','C','C'),value=c(1,2,3,4,5,6))
ggplot(data=df,aes_string(x=x, y=y)) + geom_boxplot()

The reason is that aes allows the first two arguments to be unnamed and
are assumed to be x and y (respectively); aes_string does not have this
shortcut, and so all arguments must be named.

args(aes)

function (x, y, ...)

args(aes_string)

function (...)
