What file are you putting these into? I believe this is the correct syntax for the \example{} section of an .Rd file. If you want to do this in a plain R file, (e.g. package/tests/somename.R), you can use if(interactive) { num_reps <- readline(""How many reps do you have... ") num_reps <- as.integer(num_reps) } else num_reps <- 10 instead. -G > -----Original

Hi all, I've got a matrix of fractional data that is all positive and greater than zero that I would like to "loosely" classify, for lack of a better word. It looks something like this : 1.07 1.11 1.27 1.59 0.97 0.76 2.23 0.98 0.71 0.88 1.19 1.02 What I'm looking for is a way to round these numbers to the nearest 0.25, i.e. the above matrix would be

Hi all, I've got a script that generates a few moderate-size data frames, and then puts them together into one big data frame at the end in order to write that data frame to disk, so that it may be re-opened later on... I'm trying to trim down memory requirements in this script, so I was wondering if there was any way to append to a data frame already saved on disk (just like

Dear list, When I run an R CMD check --as-cran on my package (pROC) I get the following note: > Uses the superseded package: ?doSNOW? The fact that it uses the doSNOW package is correct as I have the following example in an .Rd file: > #ifdef windows > if (require(doSNOW)) { > registerDoSNOW(cl <- makeCluster(2, type = "SOCK")) > ci(roc2,

Hi all, What I'd like to do is to is to be able to extract a string corresponding to only the file name from a string containing the complete path, i.e. from the following path string: "/Users/ken/Desktop/test/runs/file1" I would like to end up with: "file1" This would be most ideally done in a platform-independent way. Thanks in advance, -Ken

Hi all, I've got a data frame that has an identical column to a chr vector. I would like to use the chr vector to order the rows of the data frame to be identical to the order in the chr vector (the contents of the chr vector are completely identical to one col of the data frame), but this is proving trickier than it sounds.. Any help would be much obliged, -Ken

Oh, I completely missed that one. It's very neat as it seems to work both on Windows and Unix. Thanks!

Hi all, I was hoping that someone could verify this for me- when I run princomp() on a matrix, it is my understanding that the scores slot of the output is a measure of how well each row correlates (for lack of a better word) with each principal component. i.e. say I have a 300x6 log2 scaled matrix, and I run princomp(). I would get back a $scores slot that is also 300x6, where each value

[Automatic forwarding from R-bugs failed. This message has been manually forwarded.] Hi all! I'm trying to add Thomas Lumley's defmacro() function Lumley T.

And I've encountered an error in

Hello, I'm hoping that there is an easier way to rename columns in a data frame other than by using the names() assignment, which requires you to type in all the column names at once for a data.frame, in the case that I simply want to rename a single column in a data frame. Also, is there an easy way to move columns in a data frame around relative to the other columns? Thanks in

Hi all, As far as I can tell, the only canned way to do an intersect between two vectors of ints is the intersect(vec1, vec2) function -- is there another function I'm missing for intersecting more than two vectors?? TIA, Ken

Hi all, Sorry if this is a dumb question, but I am on 10.4 with R2.2, and when loading a big text file (~500MB) with scan(file, what=character) I am throwing malloc errors that say I am out of memory...I have 5GB on this machine, and Activity Monitor tells me R is only up to ~1.84GB both times this has happened (running from terminal)... I am wondering why this is happening when I still have

Is there a good strategy for testing examples which should not be run by default? For instance, I have examples which get data from the Internet. If I wrap them in try() then they can be skipped if the Internet is not available, but may not be tested in cases when I would like to know about the failure. (Not to mention that the example syntax is ugly.) If I mark them \dontrun or \donttest

Hi, source(file,echo=T) will not echo the last comment in "file" if it is the last line in the file. For instance, when sourcing a file containing the following lines #comment 1 a<-1 #comment 2 R will echo > #comment 1 > a<-1 What is the solution to have R echo all of the comment lines? Specific context: This problem arises e.g. in the context of help files (.Rd) whose

Hi again; I have placed many examples in the CTFS Rd pages because my audience really really likes lots of examples in order to understand the options available in a functions. At this time I have set them all to \dontrun{}. however, this isn't because the example command line with its function and options won't work, but rather that CTFS specific datasets must exist to have the

I have a couple of packages (?fiery? and ?reqres') that uses a mock of a rook request for their examples. The mock is an R6 object containing a rawConnection, along with a finalizer that closes this connection when the object is removed. So far so good. I?ve recently been getting CRAN errors due to the rawConnection not being closed in examples > cleanEx() Error: connections left open:

1. I often like to put bits of the output into the manual pages. (We can have a discussion of the value of this elsewhere -- I think it is sometimes a good thing.) In R I need to surround these with \dontrun{} for the sake of the tester, which is fine. But the printed output contains ## Not run and ## End (not run) comments, which defeats the purpose of the lines by breaking them

You've answered my question 2 about why the manual was in odd order > R CMD check was more of a check of the latex version of the files, not > the final manual. I was looking at the result of R CMD check, and it was in random order (perhaps file date?), not just a different collation choice. Very odd. I will cease worrying about what I might have "done wrong". I omitted the

Hi all, When using heatmap() with a pdf driver, and specifying parameters for mai in heatmap, I get a printout of the mai parameters at the top of the pdf...see attachment. This is on win2k pro with R2.2.1 Thanks, Ken

Hi all, I have a bunch of int vectors. Each vector holds a bunch of ints that correspond to row numbers of an existing matrix. I use the int vectors to pull out rows of data from a matrix, i.e. data <- my_matrix[int_vector,] I would like to store these int vectors in some sort of data structure that will preserve them as-is and allow iteration. I guess what I'm looking for would be
