I'm not sure I did anything special to install R for use with cygwin.
Availability of RCurl appears to relate to windohs AFAICT from the CRAN page.
I have never bothered to use this since I already use the related linux
tools available through cygwin. Building from source may have become an issue
lately but I started to use install.packages in an R script invoked
from a bash script running on cygwin and this has worked without incident.
R doesn't know about cygwin so you may need to use things like cygpath if you
are feeding file names to R etc but this will be an issue with most apps on 'dohs.

From: [hidden email] To: [hidden email] Subject: [R] Installing R on cygwin
Hi R users,
Thanks in advance.
Is it possible to install R on cygwin? If yes, can anyone assist me how can I install R on cygwin?
f some packages such as RCurl is not available.
Once again, thank you very much for the time you have given.
I have some wind data, model as the frequency of the wind with its strength and
What I like to be able to calculate is for some random period in time for points
a b c what was the wind strength and what was its direction.
My problem is that although I have a set of values for the rfrequency of the
wind and its strength, I do not known how it changed. For example I known the
wind blew at 10knots North, 3 times, blew 5 knots east 10 times east and 7
knots west twice , I do not known how or when it changed direction.
All of the solutions that I have looked at tend to calculate the average wind
strength and direction or deal with a single variable.
I think a more accurate version would be:
1. To derive the prevailing wind, ie the most frequeny value and direction.
2.Attempting some type of probability distribution and running that for N times,
but I am not sure how to model more than one random variable(ie the speed AND
Take option one, from my example, it gives a value of 5 knots east as its the
most frequeny, but this ignores the values for north and west.
Has anybody got any suggestions on how this could be modeled in R?
