Hi:
I am trying to build/install rparallel source package in win32 using Rtools/R
CMD. However, R CMD build or install fails. The R CMD build output shows that
the path of Rtools/MinGW/include is wrong in g++ -I. How can I pass/configure
the correct include path to R CMD? Tried this in both R
Never mind. Found the solution: the package coded the rtools path in
Makevars.win. So I was able to compile (but have another problem though). But
not sure if there is an environment name for rtools, maybe RTOOLS_HOME ...
Thanks.

This is to summarize my workaround to install R/parallel in win32/64 boxes.

I think if you attach the output file would make clear. I guess it is very
likely your merge has the problem, not the write.table. You may need "by"
parameter in merge based on the date. It also could be date value is converged
to numeric value, in this case you just need to convert it back.
Dat:
1. you can use as.matrix to convert data.frame to matrix;
2. it is likely that the internal representation of your data.frame may not be
numerical value; matrix can only take on numeric.

I have a set of user defined package which I have installed in 2.8.1 for quite

given an invalid date, I am hoping try will gen
