R-help,

R-help,

I usually call lapply to plot some dat frames structures.Something like
this:

par(mfrow=c(4,3),mar=c(2, 4, 2, 1) + 0.1)
lapply(my.list , function(x)
{
plot(colnames(x) , apply(x,2,mean),  type="o", pch = 16, ylab = "Index"
, xlab = "")
}
)

But it is difficult for me to put a title on every plot according to
the list names.
I guess the re other ways to do it but the structure above is so handy
to me that I want to stick to it.

Any suggestions?

Thanks in advance

I do not fully understand your example but if you need to act on the
columns of a dataframe why don't you just call its columns the title 
you
want. something like
X<-matrix(rnorm(1000), ncol=4)
colnames(X)<-c("foo", "foo1", "foo2", "foo3")
X<-as.data.frame(X)
par(mfrow=c(2,2))
lapply(colnames(X), function(x) plot(X[,x], ylab="y", xlab="x", 
main=x))
