Perhaps, I should use gsub as you suggested all and if the string is composed
of chars followed by numbers, it will return the 3rd part empty?

I don't think that this is about prompts in interactive R, but when a

Surely that should be left up to the user. And as Erin pointed out in

Current version of Rattle (3.1.4) supports sub= in fancyRpartPlot() to
override or get rid of that useless title, as in:

Install it using:

Unfortunately your suggestion to use remove.packages did exactly the reverse of

I have cleaned up my installation but still have trouble getting rJava to

I’m using R 3.1.0 in OS X 10.9.4 (Mavericks)
I’m running a function Y that calls a function X which occasionally generates a

Say that I call the function X 1000 times, and out of these 1000 times I get

Great.
I also said I see the point of keeping prompts, and that is why the
chunk option prompt=TRUE is provided in knitr. I may not agree with
your preference, but that does not mean I should stop you completely
from having your own preference.

This is one of those times when you would do better to just use a loop. It will
be easier to debug and to see what is going on. Replace the sapply() call with
for (i in 1:length(ind)) {
postscript(names(ind[i]))
par(mar=c(6,8,6,5), cex=0.8)
Did you ever manage to solve this problem, Jamie?

While youre at it, assign length(ind) to a variable before starting the loop.
Otherwise length() is called at each iteration. e.g.,
ind.length - length(ind)
for (i in 1:ind.length) {
etc.

Hi Keith,
So the plot thickens. How is it that you have R 3.1.1 but apt-get
install rJava gives you an old version of the package? This may be
potentially difficult to figure out, but you can try some easy things
first. If I were you I would start with
sudo apt-get remove r-base r-devel
sudo
The range vector is evaluated at the start of the loop, so it is only evaluated
once. ind.length would be an unnecessary extra variable.

Even better is to replace
for(i in 1:length(something)) {}
with
for(i in seq_along(something)) {}
The former gives you 2 iterations, the 2nd probably causing an error,
when length(something) is 0. The latter always gives one iteration
per element of 'something'.
