Hi all, I want to do this kind of function In R enviroment : For example : R <- 4 testString <- "I love $R" then search this testString, when find "$R",replace "$R" to R ,and because the value of R is 4 So the final string I want to get is "I love 4" How can I implement? Thanks advance Michael

mytest<-function(x,f){ sum(x*f)/sum(f) } cat(mytest,file="c:/mytest.R") Error in cat(list(...), file, sep, fill, labels, append) : argument 1 (type 'closure') cannot be handled by 'cat' how can i write the mytest function into a file c:/mytest.R with cat function?

Hi All, I'm working on a class example that demonstrates one way to deal with factors and their labels. I create a function called myLabeler and apply it with lapply. It works on the whole data frame when I subscript it as in lapply( myQFvars[ ,myQFnames ], myLabeler ) but does not work if I leave the [] subscripts off. I would appreciate it if anyone could tell me why. The program below

Hi all, i was using bdrb a while ago and it wasn''t stable enough in version 0.2.1 for doing the job - it loss jobs or did execute only the first one invoked and so on. Now i gave the new version a try and i found a bug at playing around. When i start a worker_method over the normal Unix scheduler bdrb will start as much as possible the worker_method after the :end-time is reached.

Hi, I added the "tests" subdirectory and a test file (say "myTest.R") to our "systemfit" package. Up to now I create the "myTest.Rout.save" file with > R CMD BATCH --vanilla myTest.R myTest.Rout.save However, "R CMD check" reports two differences between myTest.Rout.save and the output of myTest.R: a) myTest.Rout.save contains following

Full_Name: Ben Saville Version: 2.1 OS: Windows XP Submission from: (NULL) (152.2.94.145) I'm using the gsummary function to calculate a sum of V1 (column one) from my data 'mytest' by group (V2,or column 2). If V1 (the variable of interest) is all the same value (in this case all 2's), I do not get back the correct summation. If there is at least one difference in V1 (all

I''m new to rspec and looking for way to test a validation I added to a model. The test checks to see that if field1 has a value then field2 must be nil and vice versa. ------------------------------- When I did the rspec_scaffold it generated one test which worked before :each do @valid_attributes = { :field1 = "value for field1" :field2 = "value for

Hi, I was in under impression that rsync 3.0.5/3.0.6 creates all the missing directories in the path but I think I am wrong. Could any one tell me is it possible to create all missing dirs in path at destination side if not exists. Currently, I have been getting below errors. rsync -avz /tmp/mytest/rsync-test/dir-test/parent-dir/ desthost:/tmp/mytest/rsync-test/dir-test/parent-dir/ sending

When using the ARM cross compiler we've run into an issue with LTO and optimized libraries. Consider you have an optimized library opt.a, which contains a version of memcpy. Compiling with LTO (something like), clang myTest.c opt.a -flto -o myTest causes myTest.c to get compiled to bitcode. Then the bitcode gets passed to the linker. The linker looks through the bitcode (via

Folks, While going through a quick tutorial on zfs, I came across a way to create zfs filesystem within a filesystem. For example: # zfs create mytest/peter where mytest is a zpool filesystem. When does this way, the new filesystem has the mount point as /mytest/peter. When does it make sense to create such a filesystem versus just creating a directory? # mkdir mytest/peter Thank you in

Hi, Suppose I have a data.frame like this Lines <- "var1 var2 var3 var4 var5 var6 0 2 1 2 0 0 2 3 7 6 0 1 1.5 4 9 9 6 0 1.0 6 10 22 3 3 " DF <- read.table(textConnection(Lines), skip=1) names(DF) <- scan(textConnection(Lines), what = "", nlines = 1) How do I find the

Hey everyone, I know that I can call 'R' from other scripts, and that I can make command calls from 'R' (e.g., using system() ). But how can I get 'R' to RETURN values to the script that called it. E.g., I would like to be able to do something like the following (as a simpler example) from a bash script: #!/bin/bash myTest=echo /usr/local/bin/R --no-restore

Hi everyone, Can someone please help me in these questions?: 1)if I use crossvalidation with svm, do I have to use this equation to calculate RMSE?: mymodel <- svm(myformula,data=mydata,cross=10) sqrt(mean(mymodel$MSE)) But if I don’t use crossvalidation, I have to use the following to calculate RMSE: mymodel <- svm(myformula,data=mydata) mytest

Suppose I create an R program called myTest.R with only one line like the following: type <- as.integer(readline("input type (1: type1; 2: type2)? ")) Then I'd like to run myTest.R in batch mode by constructing an input file called answers.R with the following: source("myTest.R") 1 When I ran the following at the terminal: R CMD BATCH answer.R output.Rout it failed

Hello, My colleague and I would like to write Java code that invokes R to do a simple TTest. I've included my sample java code below. I tried various alternatives and am unable to pass a vector to the TTest method. In my investigation, I tried to call other R methods that take vectors and also ran into various degrees of failure. Any insight you can provide or other Web references you

List Members, I am using R 1.3.1 for windows and trying to capture the output of some summaries using textConnection. I then want to incorporate the text with summary graphics output. The code below works (captures the output) when it is not used in a loop or function. When placed in a loop or function, the cat outputs are captured to 'foo' but the summary outputs are not. The

I've got an odd problem. My server will not shutdown normally because the AoE driver is not being shut down properly. While investigating the problem, I found that the aoe script is apparently not being called for shutdown. I have been able to duplicate this with a brand new test script. My test script is just a simple file that echos back the start or stop command: #!/bin/bash #

The akima package has a problematic license (it doesn't allow commercial use), so it's been recommended that people use the interp package instead. When I use interp::interp instead of akima::interp, I get reasonable output from your example. So that's another reason to drop akima...
