In <R 1.8.1 the following fragment worked properly, now (1.8.1) it creates the following warning/error: Any advice appreciated. stt <- data.frame() # load all datasets into a dataframe for (ds in 1:n) { stt[ds] <- as.matrix(read.table(fileList[ds])) } -- > stt <- data.frame() > # load all datasets into a dataframe > for (ds in 1:n) { + stt[ds] <-

Is there a list of all contributed R libraries available through CRAN? Ideally it would include a one or two line description. I am looking for a packages() command similar to library() but that would access the CRAN repository and provide a listing of the current libraries, and version. example: http://www.cpan.org/modules/01modules.index.html

I am rendering a plot using boxplot, mtext, abline, etc. The X11 view of the plot looks correct. When I change to the png device to: png(filename="bxplot.png",width=640,height=640) I get half of a character label plotted in the lower left corner in the resulting .png file. The character fragment started to appear in png when I started using mtext.

# CASE 1 # The following plots a single cell or block for all three location 0,1,2. y <- rep(2,8) hist(y) # why is this a single block? hist(y,xlim=c(0,2)) # same thing hist(y,breaks=2) # same # CASE 2 # adding a different value, plots as expected y <- append(y,0) hist(y) # plots as expected In most cases of the data I have variances in the data so

I am performing this sequence barplot title legend abline When abline renders the lines they appare to be in the layer above the bars in the graph. Is there a way to make them render first or 'behind' the bars? Thanks.

I have my own set of labels for the X axis and typically apply them to other plot modes using: axis(1,at=1:n,labels=xLabels) Where n is the number of character strings in xLabels Is there a parameter to disable plotCI from creating its default labels for the X axis?

A number of the threads that occur in this mail list are excellent descriptions of usage patterns with R. Is anyone developing a catalog of these? The recent 'try' thread and many others are examples that may have value as a separate document or to be merged with the package help documentation.

As a linear axis I obtain the correct number of intervals for the tick marks. > source("test-lin.r") > par("yaxp") [1] 0 20000 4 However log returns 1? > source("test-log.r") > par("yaxp") [1] 1 10000 1 > I'll use log10(par("yaxp")[2]) for now. I was wondering why '1' is returned instead of 4. Thx.

Goal: adjust overlapping 'text' items in plot so they are legible I have located 'space' as one possible technique for decluttering text positions on a plot. I would rather not jitter the plot point, just the text nearby. Are there other techniques or functions available that declutters a plot using 'text'? Perhaps an arrow or a line to the plot mark could be used to
