[R] X-axis labels in histograms drawn by the truehist function

2006-10-02 Thread Ravi Varadhan
 

Hi,

 

I had sent this email last week, but received no reply.  So, I am resending
it - please excuse me for the redundant email.

 

I have a simple problem that I would appreciate getting some tips.  I am
using the truehist function within an apply call to plot multiple
histograms.  I can't figure out how to get truehist to use the column names
of the matrix as the labels for the x-axis of the histograms.  

 

Here is a simple example:

 

library(MASS)  # this contains the truehist function

X - matrix(runif(4000),ncol=4)

colnames(X) - c(X1,X2,X3,X4)

par(mfrow=c(2,2))

apply(X, 2, function(x)truehist(x))

 

In this example, I would like the x-labels of the histograms to be X1,
X2, etc.

 

Any help is appreciated.

 

Best,

Ravi

Try this:

f - function(x,xlab) truehist(x, xlab = xlab)
mapply(f, as.data.frame(X), colnames(X))
