Perhaps the following does what you want. It extends
each element of your list to a common length, converts
that to a matrix, then to a data.frame:

nCol <- max(vapply(data, length, 0))
data <- lapply(data, function(row) c(row, rep(NA, nCol-length(row

Unfortunately the "rounding effect" (which I assumed was related to
the automatic conversion from integer to numeric) is only going to
show up above 2147483647L, so I question whether you really
demonstrated a solution to what I understood was the fundamental
problem.

Thanks a lot, Steve!
match sounds very promising - that means I only need a loop across predictors.
As far as "get more memory" advice is concerned: I already have "more" memory :)

Dear List,
is there any way to test for certain conditions during the whole r
session or after the execution of each command? I am debugging my code
and sometimes a certain logical error causes a program error much later
in the script/function so especially with loops etc it is hard to
backt

It is common that performance problems are addressed by using more memory. If
your algorithm needs to join those tables and do calculations, then you can
either pay the piper in memory (usually the most appropriate answer) or you can
reinvent those optimized algorithms in a compiled language and

Dear group,

I am struggling whether I should learn Spotfire or not. I just want some

Thanks for the input, but I can confirm the either form of the paste command
i.e. expression(paste("Length (", mu*m, ")")) or my original which had
expression(paste("Length (", mu, "m)")), and the expression command alone have
the same effect. It may be limited to Linux machines

Dear R users,
I have been using R for 10 years, and I love it very much. But in my daily
job for drug discovery, some people use Spotfire. I tried Spotfire on
couple of data sets. It sounds I still need do some data manipulation
before plot figures. For example, I can not plot figure with data arr
If performance is an issue, I think mean(x < y) will be as quick as it can be
done in R alone (you could do it in C in a single pass if needed which might be
a good first exercise in using compiled code)
