There are many ways how to import whole file by read.* commands but you
could also check scan or readLines functions. The result always depends on
looklike of your input file (separators, decimals, missing values etc.)

Thank you for this!
I had also wanted in the past to do this, and ended up writing dummy
files with informative names to a folder I set to collect these
messages, so I'd check the folder to see the new files being
generated... It did the job, and at the same time I could see how long

Unfortunately the "shorter" version does not do what the op asked.
The correct way is using the 'collapse' parameter. Using paste on a
vector of length n with the parameter 'sep' you get a vector of n
elements. If you use "collapse" you get a single string.

Hi everyone,
is there a way/package in R that would allow me to select a group of
points from a scatterplot by drawing a circle around them or some such?
I can use 'identify' to pick individual points, but that gets tedious
if one has more than 10-20 spots.
I can easily select spots within
Concise and perfect answer. Thanks!
I'm surprised I never came across this issue before (4 years playing with R).

Hello list,
I use R for microarray analysis.
One procedure I use takes a large matrix, and loops through it looking
for specific rows, does an operation with them, and outputs a result
(single row) as a row of another matrix. The loop goes on about 25000
times.
When I run the loop direct
