multi process support in R
Dear all,
two days ago I was trying to run a bunch of adaptIntegrate() functions (double integrals) into my 4 core pc.
As I was not satisfied about my pc's performance I tried also to run my code to another computer that has 8 or 16 cores. Unfortunately I didnt get any really decent improvement . In both computer only the first core was looking busy while the rest were close to idle levels.

GPS handling libraries or (String manipulation)
Dear all,
I would like to ask you if R has a library that can work with different GPS formats
For example
I have a string of this format
N50° 47.513 E006° 03.985
and I would like to convert to GPS decimal format.
that means for example converting the part N50° 47.513
to 50 + 47/60 + 513/3600.
Is it possible to do that with R?
What is the name of such a library?
I would like to thank you in
