similar to: Use apply on a function with multiple argument including a matrix ?

Hi: I was trying to use apply on a sparse matrix from package Matrix, and I get the error: Error in asMethod(object) : Cholmod error 'problem too large' at file ../Core/cholmod_dense.c, line 106 Is there a way to apply a function to all the rows without bumping into this problem? Here is a simplified example: > dim(sm) [1] 72913 43052 > class(sm) [1] "dgCMatrix"

Hello, I am trying to get the output from the numerical simulation of a system of ordinary differential equations for a range of values for three parameters. I am using the ode() function (deSolve package) to run the numerical simulation and apply() to run the simulation function for each set of parameter values. I am having trouble getting the apply() function to work. Here is an

Dear list, I am trying to plot histogram of a 10 by 5 matrix by columns.

Hello all, I am trying to use computer modern fonts in my r grahics. I tried to do, as described here: http://www.stat.auckland.ac.nz/~paul/R/CM/CMR.html but unfortunately, it does not work. First of all I downloaded the cm-lgc package and the AFM and PFB-files from the page and put them in my R working directory, so far, so good. Then I tried to run the following code: > sn <-

Hi R-Users, I am working with sm.ancova (in the package sm) and I have two problems with the graph, which is automatically generated when sm.ancova() is run. 1-Besides of the fitted lines, the observed data appeared automatically in the graph. I prefer that only fitted lines appear. I check the sm.options, but I could not find the way that the observed data do not appear in the graph. 2-I

Thank you for reply Rowland. Sorry for my typo. I intended to change sm--to-->test but i forget to change other lines. So my original config is below: workgroup = sm > realm = sm.pvt > server string = %h Test Host > security = ads > encrypt passwords = yes > idmap config sm.pvt : backend = ad > idmap config sm.pvt :

I am a bit worried I am reinventing the wheel. Isn't there a calendar system in R? I have written a function to add months to a date and return the number of days resulting. I am newish to R so I am hoping there is a package that can do this sort of date arithmetic for me... Worik DaysInMonths <- function(s,d){ ## Days in d months from s sdate <- MSTD(s) ## Get day, month

Any troubleshooting steps I can follow to get this SR attached again?

Today I tried to install the R-2.5.0 (currently running R-2.4.1) on Mandriva Linux. The ./configure and make commands seem to run fine, but "make check" gives the following messages: running regression tests make[3]: Entering directory `/home/ethomp04/R-2.5.0/tests' running code in 'reg-tests-1.R' ...make[3]: *** [reg-tests-1.Rout] Error 1 make[3]: Leaving directory

Currently when R starts up it can be configured by a file of environment variable specifications and a file of R code. This makes programmatic modification of startup configuration tricky. Case in point: I start R, do install.packages("foo"), and up pops the 'choose a CRAN mirror' dialog. I'd like to put a 'Save my choice' button on that dialog. Currently it would

Hi, Nice to receive your suggestions. Follwing the suggestions, the xapi service does work on a non XCP host and most of the xe interface of get information (such as "xe vm-list ")can work well. However, when I used the "xe sr-create" interface to create a SR, I got a error "The SR could not be connected because the driver was not recognised ". I noted that

Hello everyone,          Dr. wood told me that I can adapting his example to force cubic spline to pass through certain point.          I still have no idea how to achieve this. Suppose we want to force the cubic spline to pass (1,1), how can I achieve this by adapting the following code? # Penalized example: monotonic penalized regression spline ..... # Generate data from a monotonic truth.
