[R] Using a function to consolidate variables

Dear List, I'm getting the error: object of type 'closure' is not subsettable And am not sure how to get around the problem. I've included two short code sets below. One that shows what I want to do and works, but without using the function much, and another that tries to use the function but

Hi Jim, thank you for your reply. Apart from win.metafile(), is there some other function available which can handle multiple prints or par(mfrow=c(2,2)) command and eventually can be used in powerpoint/word. thanks, Kim On Thu, Mar 18, 2010 at 12:42 PM, jim holtman jholt...@gmail.com wrote:

Hi,  Does anyone know of an existing package that will output to rtf?   Something along the lines of pdf(ds,'file.pdf') or write.csv(ds,'file.csv'). You could use odfWeave and then use OpenOffice to generate an RTF file. Regards, Tom __

[R] strptime(): on Linux system it seems to call system time?

Dear List, For what I understand, strptime() simply converts from one class representation to another; i.e., from character to POSIXct/POSIXlt. One strange feature of this command running on Linux is that there are repeated calls to system time (as was revealed in a trace of system calls),

Re: [R] multiple print commands in win.metafile()

It depends on what you want them for. With win.metafile, what is the problem with multiple files? You can still include them in powerpoint/word. If you want it in one file, then use PDF and you can cut/paste the graph from the pages that you want. I typically create a PDF file if I have a

It occurs because the two series have times that are slightly different. For example, it may appear that the times at positions 909 and 910 are the same but in fact they are different: tt - time(zoo.ts.cor)[909:910]; tt [1] (03/09/09 12:30:00) (03/09/09 12:30:00) diff(as.numeric(tt)) [1]

Many thanks to everyone who helped me solve this problem. I think I must have described my problem poorly, but Phil, Patrick and Jim were able to see through the haze and suggest that I use a list to contain the output from my loop. This solution works very well. Thanks again for your help, Mark
