similar to: Creating packages

When trying to update packages after the sysadmin updated R on my unix box I got errors on some packages. For example for chron: * DONE (chron) mkdir: cannot create directory `/usr/lib/R/library/00LOCK': Permission denied ERROR: failed to lock directory '/usr/lib/R/library' for modifying I got similar messages for spatial and cluster and warnings for other packages. Finally I got:

I have had a problem with stripplot. Documentation does say that method ="stack" is only appropriate for granular data, but I don't think that means it should fall over. > difference [1] 2.0 1.3 2.8 -2.6 -0.4 -0.4 -1.2 -1.4 -1.0 1.2 -2.6 -1.9 > stripplot(difference) > stripplot(difference,method="jitter") > stripplot(difference,method="stack")

I am using r0.63.2 for Windows. This seems like it should be a FAQ but I couldn't find it in the R FAQ. If I want to have different workspaces for different projects how do I arrange for R to restore a workspace from a directory other than the one where the executable is, automatically on startup? Is it possible, or do I have to save the workspace in the right directory then manually restore

I am using rw0.63.2. I haven't upgraded because we use R for teaching. Students use R at home, and we don't want to change them over in midsemester. Also we have some additional functions we use, and we need to test them before we start to use a new version. Which brings me to my question. To help with testing we are preparing a test file which will run through all our examples. In the

I'm experiencing a new and annoying phenomenon which seems to consist of an unfortunate interaction between R-1.7.0 and netscape version 7. When I invoke help.start(), a netscape window duly appears with the browser pointed at the file .../R/doc/html/index.html as one would hope and expect. However if I then ask for help on a function, e.g. > help(glm) the help does NOT get displayed

I want to do some recoding of variables: code Age into groups and recode a factor into a smaller number of levels. There are a couple of options for recode functions, in the car package and in memisc, and I think in gmisc. Does anyone have any opinions on the the easiest, most reliable approach for these problems? David Scott _________________________________________________________________

I am looking for a recommendation for an open source competitor to Winzip. I seem to recall Brian Ripley mentioning one in the last year or so, but couldn't find it in the mail archives. (Searching on Ripley there is somehow not terribly useful.) Suggestions?

I have encountered a problem with reading a .csv file on a linux box. I can read the file on my windows machine (under XP) but on the linux box it gives : > patients <- read.csv("../Patients.csv", header = FALSE, + col.names = patientsNames) Error in type.convert(data[[i]], as.is = as.is[i], dec = dec, na.strings = character(0)) : invalid multibyte string

I am trying to create a plot similar to Figure 3.2 in Bates and Pinheiro. I have repeated measurements on about 80 subjects from 2 treatment groups. I would like to have the panels for the two treatment groups in separate groups and within those groups have the panels ordered on maximum value (as is the default). I am ok with getting plots similar to Figs 3.1 and 3.2, but can't see how to

I have around 4000 observations of a time series. I am trying to fit a regression with ARMA error structure using gls from the package nlme. I have encountered the error: cannot allocate vector of size 126064 Kb I know this has come up many times before and I will check out the suggestions in the mail archive. I was wondering though if there is an alternative package that will fit such a

I have a data set concerning ferritin levels in blood. There are three relevant columns for this question, ferritin (continuous), score (ordered, from 0 to 8) and gender. There is a good linear relationship between log(ferritin) and score for each gender. I can create a lattice plot on the log scale showing the data and the fitted line: xyplot(log(ferritin) ~ total|gender, data = blood,

Delving into the murky world of dates and times I found this: dates <- c("02/27/92", "02/27/92", "01/14/92", "02/28/92", "02/01/92") > times <- c("23:03:20", "22:29:56", "01:03:30", "18:21:03", "16:56:26") > x <- paste(dates, times) > z <- strptime(x, "%m/%d/%y

I am analysing some data collected over a number of months from Allentown, PA, which is just north of Philadelphia. I am using as.POSIXct for dates and times, and I need to get the timezone specification correct. Going on the documentation for DateTimeClasses, I believe one way to specify the correct time zone is tz="EST5EDT" I would be grateful for any advice on this. I ask

I have just got a new machine and had a basic cygwin installed before it was given to me. It didn't include make. Previously I have installed Rtools to build packages and now I have got myself a bit confused as to whether to just install make from the cygwin packages or to install rtools. I would welcome any advice. I had a look at the rtools section in the Administration Manual and the

I am having trouble with try and tryCatch. I have read the documentation but I just don't get it. Here is what I am trying to do. I am testing a function which has a number of parameters. I want to test it for different values of the parameters and I have some loops, in the middle of which is a test of the function. Sometimes the routine fails and so I have put the bit that might fail

This is really a query about MySQL which I am trying to use to set up a database which I will then access with RODBC. I have my data in a .csv file, and some of the fields are date/time fields. I tried to create a table using mysql with the definition of the date/time field given by CallDate DATETIME, but I got an error saying that the first row has 28/07/2006 0:00 in that field. What I

I am aware of one (unofficial) guide to style for R programming: http://www1.maths.lth.se/help/R/RCC/ from Henrik Bengtsson. Can anyone provide further pointers to good style? Views on Bengtsson's ideas would interest me as well.

Hello, I would like to know if it is possible to insert LaTeX typesetting in R output. I want to obtain a graph with LaTeX label in order to incorporate it as postscript or pdf, x<-seq(0,1,length=100) y<-x*x plot(x,y,xlab="$X$",ylab="$X^2$")
