create a index.date column
Dear
R users,
I
created a matrix that tells me the first day of use of a category by
id.
#Calculate
time difference
test$tdiff<-as.numeric(difftime(as.Date("2002-09-01"), test$ftime, units = "days"))

obtain the index date per person and dcategory

list(test$id, test$rcat), max)
Nonetheless,

T <- matrix(c(rep(NA,length(n)*ncol(data))), nrow = length(n),
ncol=ncol(data), byrow=TRUE)
Tdiff<- matrix(c(rep(NA,length(n)*ncol(data))), nrow = length(n),
ncol=ncol(data), byrow=TRUE)
T1<- c(rep(NA,ncol(data)))

Building from a source-code library under windows
Dear All,
I have a pair of .cpp and .def file can be compiled using VC++ and works
perfectly well in S-PLUS.
I wanted to do the same for R; so I followed the guidline given in "Building
from a source-code library under Windows" as much as possible and manage to
compile them using VC++ and call it from R. But it gives different answer
from the one called from S-Plus.
I know that I did

type traits bug in clang 4.0.0?
Dear all,
I found this strange behavior, when inspecting some legacy build that did
not compile after an upgrade of several libraries and clang:
https://stackoverflow.com/questions/44846377/what-is-the-reason-behind-instable-type-traits
I got no conclusive answer, but a comment that indicates that this might

I wrote to r-help about this and was appropriately told off by Peter

Following Peter's advice I have attempted to simplify the problem.

Amazon Marketplace AMI
Hi,

for using CentOS on AWS.
Regards,
Thorsten
PS: It would also be great to have a CentOS 6 AMI with HVM
