Hello! I am experiencing a problem with section 3 of the code below. I want to generate barplots (based on data generated in Sections 1 and 2) in a loop - for each variable in "data" - and save them as .emf files in my current directory. But it's not working - it's printing values to be plotted to the screen but does not print the plots themselves anywhere (and not in the

Hello! I promise I looked into help files before asking. Still cannot figure it out. I think it's because I am totally confused what packages use lettice, which use trellis, etc. Sections 1 and 2 below produce the data and the data to plot. My question is about barplot in Section 3. I am trying to: 1. add only horizontal gridlines and manipulate the type and color of that line. tck = 1 is not

Hello All, Hope people won't mind my posting a LaTeX question here. I know a lot of people who use R are also using LaTeX. I'm in a bit of a rush to complete a document and am having trouble with one aspect of the formatting. I'm creating a list of tables using: \listoftables I also have some table captions that contain the number of patients in an anlysis like: \caption{Results

I'm using the levelplot function in the lattice package. I am plotting a grid of cells and I want grid lines drawn between cells. I've spent a lot of time trying different options. I've also looked at panel.levelplot. The border parameter seems to be ignored or it doesn't mean cell border color. The panel.levelplot calls grid.rect but forces lwd=1e-5 instead the passed lwd. On

I'm trying to rename the columns in a list of data.frames using the following... for(i in 1:length(filenames)) { assign(names(get(filenames[i])), c("name", "infood", "time") ) } R returns no errors, but the names are unchanged in the data.frames. The original names were things like > names(get(filenames[2])) [1] "Tc45w4.V1" "Tc45w4.V2"

Dear all: Does anybody know about label conflicts between xtable and Hmisc? I found a couple of e-mails similar to this problem but is not clear to me how to get around the label problem. The first table(longtable below) is generated with the latex function from Hmisc but for some reason when I try to hyperlink to it,it takes me to the top of the document. The second table created with the xtable

I am wondering if it is possible to read.table repeatedly from a list of file names into a new list of table names. For example: filenames <- list.files() then with a function like rf <- function(i) { word??(filename[i]) <- read.table(filenames[i]) } I can't seem to find a function like word?? that will be the object of another operation. If this worked, then I could repeat

I'm using R (2.4.1) and Hmisc (3.3-1), and I'd like to plot confidence intervals using xYplot and smean.cl.normal (or smean.cl.boot) from Hmisc. You can do that using the summarize() to produce a new data.frame and then plot with xYplot, or by specifying method=smean.cl.normal in the xYplot. Both produce very similar graphs in all trivial examples I've tried, but not in the attached

Hi, I am a new user of R 2.8.1. I use Tinn-R for code editing. I use a windows 2003 system with 1 GB RAM. I am interested to generate dashboard and reports based on data from MS Access. These reports need to be posted on a weekly basis to the web. The reporting interface should provide facilities for "what if" scenarios. Is it possible to interface R analysis results to good open
