similar to: row.names(data.frame(matrixWithDimnames)) depends on first (PR#13244)

Full_Name: Bill Dunlap Version: R version 2.9.0 Under development (unstable) (2008-10-29 r46795) OS: Linux Submission from: (NULL) (76.28.245.14) When data.frame() is given a matrix with rownames, then the type of the output row names depends on whether the first element of the input row names is "" or not. The other elements of the input row names don't affect things. E.g.,

Hey everyone! I am seeing strange behavior with NA in the rownames of dataframes: > a <- data.frame(1:3, row.names = c("r1", NA, "r3")) > cbind(a) X1.3 r1 1 <NA> 2 r3 3 Everything works. The peculiar thing is that when the NA is in the first row, things no longer work as I would have expected: > b <- data.frame(1:3, row.names

Someone said it used a possibly platform-dependent higher-than-double-precision type. By the way, in my example involving rep(1/3, n) I neglected to include the most precise way to calculate the sum: n%/%3 + (n%%3)/3.

In the past few years we have been working on making it possible to use packages in both R and Spotfire S+ (previously officially called S-PLUS). One problem was that certain lines in the DESCRIPTION file of a package needed to be specific to R or Spotfire S+. E.g., if your package used the xyplot() function then the package would depend upon lattice in R and trellis in Spotfire S+, or a package

R version 2.10.0 Under development (unstable) (2009-09-08 r49628) Here are two somewhat related questions. First, when we attach a too short names vector to a vector the names vector is padded with NA's to the length of the main vector: E.g., > x<-1:3 > names(x)<-c("One","Two") > str(x) Named int [1:3] 1 2 3 - attr(*, "names")=

In R versions 2.10.1 and "2.11.0 Under development (unstable) (2010-03-07 r51225)" on Windows I get the following if I type the commands at the start of the session. Note how the attribute attached to the name "Response" by the initial call to structure() seems to get tied to that name for the remainder of the session: > z <- structure(quote(Response),

With most sorts of objects the following three expression have the same value: names(obj) attr(obj, "names") attributes(obj)$names However, for call objects the last gives NULL, whether there are names or not. > obj <- quote(func(one=1)) > obj func(one = 1) > names(obj) [1] "" "one" > attr(obj, "names")

Dear Will, This is exactly what I find. My point is thus that the sum function in R is not a naive sum nor a Kahansum (in all cases), but what algorithm is it using then?

Hi Bill, The thing is that is happening here is the specific instance of as.data.frame that is being run, which in this instance switch between as.data.frame.matrix() and as.data.frame.matrix(). I attached the dataframe.R code, which you can find the src/library/base/R folder of the source code. Though if you use data.frame() it will give a more expected result. For instance the first runs

Here are a couple of problems with the use of eval.parent(substitute(expr)) instead of just lazily evaluating expr in the .doTrace function used by trace. (a) In S+ I sometimes use trace() to see how long a function takes to run with a tracer expression the saves the start time and calls on.exit to report the difference between the start and end times when the trace function ends.

Hello. Will, thanks a lot for pointing me to the MaskedGatherSDNode and mgatherv4i32. I have to say that the definition of the "multiclass avx512_gather" from lib/Target/X86/X86InstrAVX512.td is difficult to follow and I prefer not to use it. I currently have some serious problems with TableGen - it gives an assertion failure:

Cool, looks like that'd do it, almost as if converting an entire record to a character string and comparing strings. -- M. B. Hardy, statistician work: Applied Research Associates, S. E.
