Dear List: I am encountering an error that I can't resolve. I'm looping through rows of a dataframe to generate individual tex files using Sweave. At random points along the way, I encounter the following error Error in file() : cannot find unused tempfile name At which point Sweave halts. There isn't a logical pattern that I can identify in terms of why the program stops at

Dear R-devel, Can anyone help me to understand this? It seems that subscripting the rows of a data.frame without actually changing their order, somehow changes an internal representation of row.names that is revealed by e.g. dput/dump/serialize I have read the docs and inspected the (R) code for data.frame, rownames, row.names and dput without enlightenment. df=data.frame(a=1:10, b=1)

Maybe someone can help shed some light on an odd and repeatedly irritating error I noticed when running the check Perl script on my R 1.3 project. In following it line by line, I traced my problem down to the code/documentation matching within check, the most recent version of which seems to verify proper .Rd formatting by means of R's codoc and undoc functions. Under R --vanilla, those two

G'day all, The documentation for tempfile states : "The names are very likely to be unique among calls to tempfile in an R session and across simultaneous R sessions. The filenames are guaranteed not to be currently in use." My problem I think relates to the second part of the sentence, which is the guarantee... and it is being met ... but I need to save the files as .png files,

After checking the original data in Excel for blanks and running Summary(cm3) to identify any null values in my data, I'm unable to identify an instances. Yet when I attempted to use the data in Random Forest, I get the following error. Is there something that Random Forest is reading as null which is not actually null? Is there a better way to check for this? > library(randomForest) >

Hi all, Yesterday, I had some problems reading JPG files in my tests. Turns out the problem was that Windows Ruby doesn't set it's Tempfile to work in binary mode. Since I deploy on Linux, that has never been a big problem, but now I'm working on some software that works with binary files exclusively. Anyway, I am making this fix available as a Rails plugin. The details can be

The other day I was working on an example which used tempfile() to create file for use by the graphics device. And while I love tempfile()---as it is portable and clever and the files get cleaned by R and all that---I noticed one missing feature I would like to see: beside a starting name pattern, and an optional directory, an 'file extension' argument would be nice to have. As e.g. in

Temporary images can be quite big, more than the space available in $TMPDIR when it's on a tmpfs; hence, place them in our cachedir instead. --- builder/builder.ml | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/builder/builder.ml b/builder/builder.ml index 957bc37..3750e5f 100644 --- a/builder/builder.ml +++ b/builder/builder.ml @@ -378,6 +378,8 @@ let main () =

Hi, I'm using package "caret" to rank predictors using random forest model and draw predictors importance plot. I used below commands: rf.fit<-randomForest(x,y,ntree=500,importance=TRUE) ## "x" is matrix whose columns are predictors, "y" is a binary resonse vector ## Then I got the ranked predictors by ranking

I''ve been facing a problem when generating a model (or controller, ...). I''m using rails 2.3.8 and ruby 1.8.7.

I've built two RF objects (RF1 and RF2) and have tried to combine them, but I get the following error: Error in rf$votes + ifelse(is.na(rflist[[i]]$votes), 0, rflist[[i]]$votes) : non-conformable arrays In addition: Warning message: In rf$oob.times + rflist[[i]]$oob.times : longer object length is not a multiple of shorter object length Both RF models use the same variables, although

I'm used to Debian-based distros which have a tempfile(1) utility for safely and sanely creating temporary files. There isn't a comperable utility for RHEL/CentOS systems. I've been exercising Google-fu looking for a good robust tempfile generation idiom, but haven't turned one up yet. Hence this appeal to the lazyweb. -- Dr. Ed Morbius, Chief Scientist / | Robot

First off, I''m not trying to spec attachment_fu, I know it''s been tested. But, I added some code to that model that I do need to test. Basically, I need to somehow fulfill the "uploaded_data" property so I can actually run my tests(otherwise they fail because of validations). The "uploaded_data" field is what would grab the multipart data from form. Here

Hello, I need to be able to write a temporary file for use during the request only. Locally I can use the following successfully: tempfile = File.open(a.original_filename,''w'') tempfile.write_nonblock(a.body) paperclip stuff........ tempfile.close That works great, but not on Heroku... How can I do the above with Heroku''s restrictions:
