R2.0.1 (MS Windows) > list.files(myloc,"*.zip",full=T) [1] "P:/SARsoftware/Rlibraries/gnlm_0.1.zip" [2] "P:/SARsoftware/Rlibraries/lms2_0.2.zip" R2.1.0: > list.files(myloc,"*.zip",full=T) Error in list.files(path, pattern, all.files, full.names, recursive) : invalid 'pattern' regular expression Bug? or have I missed something

There must be a simple answer. I want to plot an expression, where the expression is held in a string variable. The "obvious" solution along the lines of ex<-"x^2" plot( c(0,1), c(0,1), main=as.expression(ex) ) gives me the a title x^2 - ie doesn't treat it like an expression. I suspect I don't understand expressions properly. For the real problem I do need to

Anybody out there successfully using the Salford Fortran compilers with R? I have created a DLL using the Salford FTN95 compiler and it works in as far I can dyn.load it, run the routines and get the right answers back. Unfortunately subsequently, sometime later, the Rgui crashes (access violation I think from the DrWatson log). The crashes depend on whether or not I paste the code as one

As I understand it lme (in R v1.9.x) estimates random effect variances on a log scale, constraining them to be positive. Whilst this seems sensible, it does lead to apparently biased estimates if the variance is actually zero - which makes our simulation results look strange. Whilst we need to think a bit deeper about it - I still haven't got my head around what a negative variance could

Greetings. One for the developers I guess... I am having problems in using a (non-recommended) Fortran compiler (Salford ftn95 Windoze), and the crashes do seem to be associated with the ftn95-dervived DLL changing the Floating Point Control Word. The compiler people are suggesting (and I paraphrase!) that if R minds what the FPCW is it is up to R to make sure it is the value it wants and

Dear all, One for the windows graphics developers I guess.... I seem to have hit a bug in the line drawing in windows (default device or explicit calls to win.metafile). As the line segments used to plot a curve get smaller (increased resolution) the line drawn seems to get less smooth rather than more smooth, and starts to break up.. Attached is a toy example drawing a quadratic with

Let me modify my question about user-defined covariance structures for LME models: Can somebody tell me how I can see the code for the definition of the correlation structures that come with the NLME package. Specifically I like to see the code for the functions coef, corMatrix, and intialize for any of the pre-defined correlation structures, and use this as a template to define a new correlation

Greetings. There seems to be a problem with the P-value computation in the cor.test with method="spearman". In R1.8.0 (MS Windows) I seem to be getting intermittently nonsense P-values, but the rho's are OK. I can get this reproducibly with the toy example attached where the first use is OK and subsequent calls with the same data give nonsense. (I have also seen the problem

Greetings, I use S+, Stata, SAS and R depending on the weather... The script file editors in S+, SAS and Stata all allow me to submit a portion of a developing script file to the running process. In R I have to use an external editor and either source the entire file or do lots of copy-and-pasting. Are there any editors out there which interface to R more closely and let me submit a section

Greetings, Before I reinvent the wheel has anyone done a profile function for a fit using optim (or nlm)? (like the buggy profile.ms in S+) . It seems a bit tricky as the function to be minimised has to have arguments corresponding to the variables being fitted - which is one less than the function provided to optim()... I guess you can create another function on the fly somehow. Cheers,

Thanks for all the replies. Looking at the specs for the processor it does not seem to have the vmx features in /proc/cpuinfo: http://www.notebookcheck.net/Intel-Core-2-Duo-T6400-Notebook-Processor.35100.0.html and the output from grep -E ?vmx|svm? /proc/cpuinfo is empty. /lib/modules/3.10.0-229.7.2.el7.x86_64/kernel/arch/x86/kvm [keith.roberts at acer-centos kvm]$ ls kvm-amd.ko kvm-intel.ko

I wasn't clear. battery.runtime.low is not a counter, but a value estimated in seconds that is decreasing conforming the battery is discharging. It's mean: How much time (in seconds) will be necessary until the battery achieve the depleted status ( http://www.networkupstools.org/protocols/sec.html#Estimated_Minutes ) . If the UPS don't have a load, this value will be higher than the

Yes, this UPS is the same. > Does battery.runtime only get updated when on battery power, or is this with a different load? > battery.runtime.low: 59940 > battery.temperature: 00 Yes, this time time is updated on battery power, This is a dynamic counter that changes with a different

Hi, I've seen posts (but no answers) about clearing a file lock on a Samba share. Presumably this kind of thing happens when the program abnormally terminates and doesn't close its open files.

Hi I am a newbie to R but have tried a number of ways in R to do this and can't find a good solution. (I could do it out of R in perl or awk but would like to know how to do this in R). I have a large data frame 49 variables and 7000 observations however for simplicity I can express it in the following data frame Base, Image, LVEF, ES_Time A, 1, 4.32, 0.89 A, 2, 4.98, 0.67 A, 3, 3.7, 0.5
