The inconsistency is that you use $<- to set the column, then [[<- to change it. Had you tried to set the column by x[[1]] <- as.character(x[[1]]) you would have seen the problem immediately (it does not work as you would have intended). If you want to be sure to turn off conversion to factor, you need to set the column to class "AsIs". My belief is that will behave

Thanks to Henrik Bengtsson, Martin Maechler, Brian Ripley, Jeff Gentry and David Brahm for taking the time to answer my questions about INDEX files in R packages. My key take-aways were: 1) All of this will be changing a lot in R 1.7.0-to-be, so don't sweat the details. 2) Many people run R CMD build before they run R CMD check. I found this quite surprising. I did not realize that R

The help for options says: echo: logical. Only used in non-interactive mode, when it controls whether input is echoed. Command-line options `--quiet' and `--slave' set this initially to `FALSE'. I don't think that this is correct for me. Consider the following session: mica|junk> ls test.R mica|junk> cat test.R cat("Why was this command

Hi, In 1.4.1, I was able to create extra "empty" rows in a dataframe as so: > x <- data.frame(a = letters[1:3], b = 1:3) > x a b 1 a 1 2 b 2 3 c 3 > x[4,] a b NA NA NA > rbind(x, x[4,]) a b 1 a 1 2 b 2 3 c 3 NA NA NA > R.version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6

Hi, I often have large dataframes with many variables and many NA's, from which I would like to subset out some rows. Here is a toy example: > x <- data.frame(a = c("x", "y", "z"), b = c(1, NA, 5)) > x a b 1 x 1 2 y NA 3 z 5 I realize that, if I know the values in x$b that I want to subset, things are easy: > x[x$b %in% c(1),] a b 1 x 1

The help page for library says that: package, help: name or character string giving the name of a package. Yet, I don't seem to be able to use a string variable here. > version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status major 1

Dear R-devel, I've made some potential extensions to writeForeignSAS in 'foreign' that I wanted to pass along if anyone is interested. I've attached the diff -u output against the version found in foreign_0.8-15 and an .R file with my changes. (In this .R file, the function is named writeForeignSAS7 to simplify testing/comparisons.) I've tried to alter the current

Hi, is there a way to retrieve the line number of where en error occurred when sourcing a file in a tryCatch statement? Is it stored somewhere accessible? It is not found in the error object. Consider the following code/output and note the difference in the traceback between source (has line number) and sys.source (has no line number). Thank you, Renaud ######## # code ######## codefile <-

I am seeing some strange behavior using save on a character vector containing a slash. If this is a bug, I will happily submit it (as a single entry! ;-) ) to r-bugs. Here is an example involving "VIA\B". > version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status

There is a bug in all.equal.character: > all.equal.character(c("A", "B", "C"), c("A", "B", "C")) [1] TRUE > all.equal.character(c("A", "B", "C"), c("A", "B", NA)) Error in sum(out) : Object "out" not found > traceback() 3: sum(out) 2: paste("`is.NA' value

Although the documentation is somewhat sketchy, I() can be used to create objects of class AsIs: > I("a") [1] "a" attr(,"class") [1] "AsIs" "character" > I(4) [1] 4 attr(,"class") [1] "AsIs" "numeric" > I(4 + 0i) [1] 4+0i attr(,"class") [1] "AsIs" "complex" > This

I am having problems using merge with all = TRUE when one of the dataframes has objects of class POSIXct. If this is a bug, let me know and I will report it to r-bugs. Here is an example: > version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status major 1

dear: when I read a Excel file(exp-11),The R project give me a error ,Just like this: ??'datafile' > write.foreign("exp-11.xls") ???list(df = df, datafile = datafile, codefile = codefile) : ??'datafile' > write.foreign("exp-11.xls") ???list(df = df, datafile = datafile, codefile = codefile) : ??'datafile' >

Hi, I see some weird behavior when loading a specific dataframe after changing the value of an enviroment variable using Sys.putenv(). Alas, I can't reproduce it from an arbitrary dataframe.

Almost all of the heavy crunching I do in R is like: > for(i in long.list){ + do.something(i) + } > collect.results() Since all the invocations of do.something are independent of one another, there is no reason that I can't run them in parallel. Since my machine has four processors, a natural way to do this is to divide up long.list into 4 pieces and then start 4 jobs, each of which

In revising the splancs package, I use R CMD check. After a number of changes to various files in the directory tree, R CMD check fails at the * checking for undocumented objects ... ERROR stage as shown below. But running undoc() in R (pointed at the Rcheck directory, not on the older version) doesn't show the same error, and grep on the Rcheck R code finds the function. I ran undoc() under

Previously the code had two places where an identical set of AAVMF paths were stored. Put this information into one place.
