Is there a method with the current tcltk library in R to call back an R function within the .Tcl("...") interpreter? I can't find anything documented, and I don't understand the usefulness of the .Tcl.callback() function. Browsing through the tcltk source code I found two functions R_eval and R_call that seem to take input from the .Tcl interpreter and parse them through the R

I had an open session working in R and I regularly save the image with save.image(). However, after a period of inactivity of a few days. I quit the session. Now, when I try to restart R and load the same image I get the following result: > load("y:/grm/sdata/.rdata1") Error in load("y:/grm/sdata/.rdata1") : an xdr real data read error occured Can someone explain the cause

Hi, I have the following code from Splus that I'd like to migrate to R. So far, the only problem is the arima.filt function. This function allows me to filter an existing time-series through a previously estimated arima model, and obtain the residuals for further use. Here's the Splus code: # x is the estimation time series, new.infl is a timeseries that contains new information # a.mle

Thanks to Martyn Plummer and Vele Samak for taking the time to answer my problem. scan certainly will do the trick. However, having taken a look at the code for read.table, it seems to me that I might be able to add in a "what" argument and then just pass it down to the call to scan. But that won't be today's project . . . Dave Kane

Ok, Here's the c code that's loaded into R as dll on windows: #include <R.h> #include <Rdefines.h> SEXP test1(SEXP col); SEXP test1(SEXP col) { SEXP col2; Rprintf("no value!\n"); return col2; } Compiles ok with bcc32 into a dll, loads into R as part of a library, I Run library(rkdb), then > .Call("test1", 2) no value! And puf! Rterm crashes.

Where can I find a package with an R implementation of the S-Plus "nlmib" general minimzation routine described in Venables & Ripley's "Modern Applie Statistics with S-Plus", 3rd Ed., pp 267 - 270?

I have been trying to run this analysis and finally want to ask for help. I am trying to run a paired t-test in which I have 19 subjects who have reaction times for 5 different conditions. The data frame has 114 rows total (6 rows for each subject representing six average reaction times by condition). Is there a way to run all paired t-tests where a paired t-test is run for every possible

Sources for versions of R as far back as 0.65, I believe, are available on CRAN. You can try to compile from source.

Hi! I have a problem of curve fitting. I use the following data : - vector of predictor data : 0 0.4 0.8 1.2 1.6 - vector of response data : 0.81954 0.64592 0.51247 0.42831 0.35371 I perform parametric fits using custom equations when I use this equation : y = yo + K *(1/(1+exp(-(a+b*ln(x))))) the fitting result is OK but when I use this more general equation : y = yo + K

Happy new year to all; A few days ago, I posted similar problem. At that time, I found out that our R program had been 32-bit compiled, not 64-bit compiled. So the R program has been re-installed in 64-bit and run the same job, reading in 150 Affymetrix U133A v2 CEL files and perform dChip processing. However, the memory problem happened again. Since the amount of physical memory is 64GB, I think

Hi.... I have a question about how to increase my memory size, could someone answer it for me?? I am using Bioconductor in R to calculate gene expression values with mas5, dchip, and mas4. I have only 18 samples, all from Affymetrix U133A Plus 2 arrays, which has ~54,000 genes. My machine equipments are: CPU P4 3.0GHz, and 1GM RAM. Somehow when I was running mas5 in R, it always showed the error

I use dChip and Affymetrix gtype to apply some genotyping functions to some microarrays data. Do you know if similar R functions exist? Thank you!

Hi everybody, I'm a new R french user. Sorry if my english is not perfect. Hope you'll understand my problem ;) I have to work on temperature data (35000 lines in one file) containing some missing data (N/A). Sometimes I have only 2 or 3 N/A following each other, but I have also sometimes 100 or 200 N/A following each other. Here's an example of my data, when I have only small gaps

One of our employees is having an odd problem with Adobe Photoshop. Files he saves with Photoshop are saved with permissions 777, completely ignoring both the create mask and the default ACL for the directory. Files he creates with other programs have the correct permissions. This has me stumped. It appears I can reproduce the problem at will. Client is Windows NT 4.0 SP6a and Adobe Photoshop

Hi, all; I know there has been a lot of discussions on memory usage in R. However, I have some odd situation here. Basically, I have a rare opportunity to run R in a system with 64GB memory without any limit on memory usage for any person or process. However, I encountered the memory problem error message like this: Error: cannot allocate vector of size 594075 Kb I got this error message while

I have 1 samba4 server setup as a domain controller for FOO.COM. I want to add a second for redundancy. I really don't want to mess this up, and I can't find a clear guide online. Can anyone tell me the proper commands? Thanks. -Aaron

I'm running samba4 from git (latest as of sep 1) on ubuntu 10.4. It's operating as a PDC, as well as hosting a shared drive. The last couple days I've noticed that my shared drives will appear as disconnected, and indeed trying to connect to the server times out. If I look on the server, there are many (50ish) samba processes all sitting there sleeping. If I use the init script to
