Hello , just a simple question from a beginner: I write the function: plotsinx <- function() { x<-seq(0,2*pi,0.01) sinx<-sin(x) plot(sinx) } I recall it: plotsinx() and the plot works properly. but then in the workspace if I want to look at the values of sinx the following error is displayed: Error: Object "sinx" not found. How to save the variables created by the function on

I have been lurking in this list a while and searching in the archives to find out how one learns to write fast R code. One solution seems to be to write part of the code not in R but in C. However after finding a benchmark article (http://www.sciviews.org/other/benchmark.htm) I have been more interested in making the R code itself more efficient. I would like to find more info about this. I have

Hi, Is there some alternative to cumsum for chron objects? I have data frames that contain some chron objects that look like this: DateTime 13/10/03 12:30:35 NA NA NA 15/10/03 16:30:05 NA NA ... and I've been trying to replace the NA's so that a date/time sequence is created starting with the preceding available value. Because the number of rows with NA's following each available

I need to find solutions to a tridiagonal system. By this I mean a set of linear equations Ax = d where A is a square matrix containing elements A[i,i-1], A[i,i] and A[i,i+1] for i in 1:nrow, and zero elsewhere. R is probably not the ideal way to do this, but this is part of a larger problem that requires R. In my application it is much easier (and much faster) to generate the diagonal and

Hi, I have a 3 panel xyplot with different variables in the y axis. I'm trying to insert a newline after "Width (cm)," in the ylab argument as in the example below. My goal is to have the y axis label broken into two lines, split after the string just mentioned. plotfun <- function() { fakedf <- data.frame(A = sample(1:100, 50), B = rnorm(50),

Hello, Has anybody been able to successfully install MS Office XP Pro in Wine? I don't care much about the whole suite, I need MS Access, but since I have a bundled cd, I don't have much choice. Apparently several folks have had similar problems in this list, and I haven't found solutions. Wine-version is 0.0.20041201-1 Debian unstable package. I'm not sure I'm starting the

Hi, Is there some alternative to the 'groups' argument in lattice's bwplot function for boxplots? Say in the example below: bwplot(yield ~ site | year, data = barley) you want to have two side by side boxplots per site, corresponding to each year in the barley data frame. Ideally, the space between boxplots of the same site should be smaller than that between boxplots of different

Hi, I'm trying to establish a connection to a MySQL database, and am using the rodbc package for it. This is in a GNU/Debian Linux box, with the corresponding Debian unstable packages. I can login to my MySQL databases from any shell and directory, so the problem is probably not there. Here's an example of what I'm doing: R> odbcConnect("test",

Hello, I'm adding a private library tree in my home directory by adding this to my ~/.Renviron: R_LIBS="~/R/library:${R_LIBS}" so that once in R: R> cat(Sys.getenv("R_LIBS"), "\n") ~/R/library:/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library Is this the best way to proceed?

Hi, One of the big decisions when writing code is how to handle dates and times. Gabor Grothendieck provided an excellent overview of the issue in his R News 4/1 (2004) article, and many users and developers are probably using it as a guide. The proposed guideline is to use the simplest class required; as Gabor put it "use Date if possible, otherwise use chron, and otherwise use

Hello, I searched the archives but could not come to a solution. I have to two columns of information t_start_cdt looks like: > t_start_cdt[1:4] [1] "2003-07-09 11:02:25" "2003-07-09 11:10:25" "2003-07-09 11:30:25" [4] "2003-07-09 12:00:25" > class(t_start_cdt) [1] "POSIXt" "POSIXlt" t_end_cdt looks like: > t_end_cdt[1:4]

Hi I'm using R 2.0 in SuSE 9.2. When I plot data as a boxplot, the boxes appear on the plot in alphabetical order (of group) rather than the order in which they appear in the data. So far, the only thing I can do to fix this is to prefix the group labels with a,b,c...etc to trick R into plotting them in the right order. Can sorting be turned off? How should I address this sensibly? Thanks

Version 1.3.1 of diveMove is now available on CRAN. Changes since previous version (1.2.9) are: o Improved formatting of code in vignette. Figure resolution reduced to satisfy package check requirements. o At least R 2.13.0 is required. o Dives occurring in "trivial wet" periods are now identified. o Improved validity checking for 'TDRcalibrate' objects.

mksmbpasswd.sh does not create accounts with the X flag in the password flags field. Does this X matter, and if so, what does it mean? It's not in the man page. ---- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | | Ryan Novosielski - Jr. UNIX Systems Admin |$&| |__| | | |__/ | \| _| | novosirj@umdnj.edu - 973/972.0922 (2-0922) \__/ Univ. of Med. and Dent. | IST/ACS - NJMS Medical

Hi All, I've the following in the logs and am wondering why they are there. I also keep getting emails from SAMBA log-deamon (or something like that).

Hi All, Perhaps you guys can help me shed some light on this 'problem' I'm facing. I recently added another NIC to my samba server. eth0(10.0.0.251) and eth1(valid dhcp address) ETH0 was added to connect to another PC that acts as the backup server. (dedicated connection) Now, Samba won't come back up.. I can still ssh into the server and all. Any ideas? I know that the wins
