Subject: Re: [R] Converting a dataframe column from string to datetime
Youâre working too hard. Use this:
tms - as.POSIXct(strptime(v, %a %b %d %H:%M:%OS %Y))
Take note of the fact that there are two types of datetime objects: POSIXct
and POSIXlt.
Your unlist() gave what seemed a strange result because you used on an âltâ
object. Had you given it a âctâ object it would have made sense. To see, try
lapply(v,function(x){as.POSIXct(strptime(x, %a %b %d %H:%M:%OS %Y))})
But using lapply() was more complicated than necessary.

[R] Issue with match.call
Hi,
I have a function that I'm writing. The arguments in the function are as follows
RFF-function(qtype, qOpt,...){}
i.e., I have two args that are compulsary and the rest are optional. Now when
my user passes the function call, I need to see what optional args are defined
and process accordingly...what I have so far is..
RFF-function(qtype, qOpt,...){
mc - match.call(expand.dots=TRUE)
}
I need to see what all args have been sent out of
vec-c(flag,sep,dec) and define if-else conditions based on whether they
have been defined. How do I do this?

When I receive the data through a client written in R, the receive is slower than the send of the server even if I'm just receiving at the client and not processing. I noticed this because the server sends records of the form rx,y,zr with each send and the client receives the record.

Re: [R] R CMD check Package(Windows): Error in inDL(x, as.logical(local), as.logical(now), ...) :
It is dependent on another dll but it did not give compilation errors. It seemed to link fine at that point. Why does it have a problem at this stage?

ERROR: loading failed The message The specified module could not be found comes from Windows. It probably means that your dll depends on some other dll and the other one is unavailable, but it might mean that AceTest.dll itself can't be loaded (permission problems, defective dll, etc.) In some cases Windows will pop up a dialog box with more information than that skimpy message, e.g. if you install the package and try to run library(AceTest) from within Rgui.
