Hello
When loading a package, I'm wondering if it's frowned upon for the
package to alter the state of the random number generator? I guess not,
since the parallel package does it?

When R is run interactively in a terminal which supports colors, it is
possible to use ANSI escape sequences in order to put colors in the prompt,
such as
options(prompt = "\033[0;31mThis is red\033[0m> ")
Unfortunately, something goes wrong because for long command lines, the
line continuation o

Surprisingly it is not frowned upon, but it *is* a nuisance.
I guess that R does not know about ANSI sequences, and it calculates the
width of the prompt including the characters in the sequences. You cannot
do much about this, except maybe use a prompt that has two lines. You can
put the colored text and whatever you like in the first line, and the
second l
Thanks for the hint. I agree with your analysis, but that still would not
explain why the continuation overrides the begining of the same line
instead of going to the next line.
I think I'll go for the two-lines prompt. If you have a Stack Overflow
account, you can post your answer and I will accep

Function 'tapply' in R devel r72137 uses
if(!is.null(ans) && is.na(default) && is.atomic(ans)) .
Problems:
- It is possible that user-specified 'default' is not of length 1. If the
length is zero, the 'if' gives an error.
- It is possible that is.na(default) is TRUE and user-specified 'default' i
Martin,
Outstanding! This is a most welcome enhancement.
