Re: [R] more than two NA value names in my data

Hi, You were on the right track with na.strings, from ?read.table na.strings: a character vector of strings which are to be interpreted as ‘NA’ values. Blank fields are also considered to be missing values in logical, integer, numeric and complex fields. so, you

Re: [R] time in year, month, day, hour ?

Dear Yogesh, This will create a vector that I believe does what you want. x - as.POSIXct(x = cumsum(c(0, rep(3*60*60, 1919))), origin = 2009-01-01) Let me see if I can explain the logic. In the innermost part, I multiply 3*60*60, or hours*minutes*seconds. You said they were three hour blocks

Re: [R] Can this code be written more efficiently?

Have you tried using Rprof to determine where time is being spent in the current code? Have you looked at how much memory you are using? Are you paging? Have you run with a size 'x', then '2x' then '4x' to see what the growth in both CPU time and memory usage is? This is what I would do if I

[R] can I add line breaks to the paste() function?

Can I add a line break to the paste() function to return the following: 'this is the first line' 'this is the second line' instead of 'this is the first line this is the second line' ? __ R-help@r-project.org mailing list

Re: [R] can I add line breaks to the paste() function?

Hello, Although on the surface a simple request, I think you need to be more specific. ?paste returns a character vector. The first question is: do you want a character vector of length 1 or 2? It sounds like you're trying to format text for display on screen or on a graphics device. Perhaps

Re: [R] interactive session

You might want to use the tcltk package so you can bring up a window in which to input your data. This is better than trying to read from the console especially when 'sourcing' in some files or when cutting/pasting. On Thu, Sep 30, 2010 at 2:55 AM, Pam fkira...@yahoo.com wrote: Hi guys, My

Try using cat instead. Then \n is the new line character. E.g. cat(1st line\n2nd line\n) Jeremy On 30 September 2010 13:30, David LeBauer dleba...@gmail.com wrote: Can I add a line break to the paste() function to return the following: 'this is the first line' 'this is the second line'

Re: [R] please help me....

Hi, I am not entirely certain how you think we can help. Many theses/dissertations are not widely published, but there is often a copy stored at the local institution's library. I would also assume that Jan Ulbricht has a copy, which if it is not available online and it is impossible for you to
