similar to: crash with NAs in subscripted assignment of a raw vector

Hi, right now we have (on R v2.7.0 patched (2008-04-23 r45466)) that: > rawToChar(raw(0)) [1] "" > rawToChar(raw(0), multiple=TRUE) character(0) Is this intended or should both return character(0)? Personally, I would prefer that an empty input vector returns an empty output vector. Same should then apply to charToRaw(), but right now we get: > x <- character(0) >

Hi, A piece of my code that uses readBin() to read a certain file type is behaving strangely with R 2.7.0. This seems to be because of a failure to match() strings after using rawToChar() when the original was terminated with a "\0" character. Direct equality testing with == still works as expected. I can reproduce this as follows: > x <- "foo" > y <-

Hi all, The dict package provides a dictionary (hashtable) data structure much like R's built-in environment objects, but with the following differences: - The Dict class can be subclassed. - Four different hashing functions are implemented and the user can specify which to use when creating an instance. I'm sending this here as opposed to R-packages because this package will

Hi, I just realized that a named empty list is displayed the same way as an empty list: > list(aa=2:5)[0] list() > list() list() For empty atomic vectors, the print method makes the difference: > c(aa=3L)[0] named integer(0) > integer(0) integer(0) Maybe lists could do that too? Thanks, H. > sessionInfo() R version 2.12.0 Under development (unstable)

Hi, > class(as(1:4, "numeric")) [1] "integer" Surprising but an explanation could be that an integer vector being a particular case of numeric vector, this coercion has nothing to do because 1:4 is already numeric. And indeed: > is.numeric(1:4) [1] TRUE > is.numeric(as(1:4, "numeric")) [1] TRUE However, 'as(1:4,

Hello, I would like to compress a long string (character vector), store the compressed string in the text field of a SQLite database (using RSQLite), and then load the text back into memory and decompress it back into the the original string. My character vector can be compressed considerably using standard gzip/bzip2 compression. In theory it should be much faster for me to compress/decompress

Dear List, I ran into some trouble handling missing values. Assume 2 vectors (numeric) including NAs a <- c(rep(seq(1,4),4),NA,NA) b <- c(sample(1:2,14,replace=T),NA,NA,1,2) I want to replace the values of vector a that are smaller than 2 and larger than 3 into NAs only in case vector b equals 1 a[b==1][a[b==1]<2 | a[b==1]>3] <- NA The following error accurse: NAs are not

Hi, cbind() doesn't seem to like raw vectors: > df <- cbind(a=integer(4000), b=raw(4000)) > df *** glibc detected *** /home/hpages/R-2.13.1/bin/exec/R: malloc(): memory corruption: 0x0000000002d73ca0 *** ======= Backtrace: ========= /lib/x86_64-linux-gnu/libc.so.6(+0x79d7a)[0x7f3592b91d7a] /lib/x86_64-linux-gnu/libc.so.6(__libc_malloc+0x6e)[0x7f3592b9431e]

Not a bug in a very strict sense, but still something to be fixed eventually: > s <- sapply(0:7, function(i) rawShift(charToRaw("my text"),i)) > s ... nothing is printed at all > str(s) raw [1:7, 1:8] 6d 79 20 74 ... > c(s) [1] 6d 79 20 74 65 78 74 da f2 40 e8 ca f0 e8 b4 e4 80 d0 94 e0 d0 68 c8 00 a0 [26] 28 c0 a0 d0 90 00 40 50 80 40 a0 20 00 80 a0 00 80 40 40 00

Hi, There seems to be a change in 2.0.1 in the workings of subscript assignments with missing values. # This is R.2.0.1 # assignment w/ missing index doesn't work when right-hand-side is a matrix. It did work in 1.9.1 > x = matrix(1, 2, 2); x[c(1,NA),] = x Error: NAs are not allowed in subscripted assignments # it does work for a vector > x = matrix(1, 2, 2); x[c(1,NA),] = 1 Is this

Browse[1]> j <- c(1,2,NA) Browse[1]> j[j==1][-1] [1] NA Browse[1]> j[j==1][-2] [1] 1 Browse[1]> j[j==1][-2] <- 2 Error during wrapup: NAs are not allowed in subscripted assignments As far as I can see, I have no NA in the lhs (not after the second subscript anyway). Besides, I have a single value on the rhs, so it should be allowed to have NAs in the lhs, according to

Hi list, This looks similar to the problem reported here https://stat.ethz.ch/pipermail/r-devel/2006-April/037199.html by Henrik Bengtsson a long time ago. It is very sporadic and non-reproducible. Henrik, do you remember if your code was using reg.finalizer()? I tend to suspect it but I'm not sure. I've been hunting this bug for months but today, and we the help of other Bioconductor

I'm trying to assign NAs to values that satisfy certain conditions (more complex than shown below) and it gives the right result, but breaks the loop having done the first one viz: new<-c(rep(5,4),6) for (i in 1:6) {new[new[i]>5.5][i]<-NA} gives the correct result, though an error message appears which causes a break if it's in a loop. If I can get rid of the error message and

Dear R users, I'm trying to perform flexible discriminant analysis (fda) with method bruto. I applied the fda function on my training data: bruto.fda <- fda (fda.formula,data=train.data) where fda.formula is: PRES ~ VA_D123 + VA_D124 + VA_D127 + VA_DARU + VA_DCAN + VA_DFON + VA_DLAP + VA_DRID + VA_DRIR + VA_VVEG + VA_WDIN + VA_DIF3 + VA_DIF4 + VA_DIF5 + VA_CAAC + VA_CABC +

I am trying to determine how to customize the date and time display of system utilities and user programs using the locale settings. What I really want is some sort of utility program that does the same thing for CentOS as the Regions Settings Control Panel app. for MicroSoft Windows accomplishes, but I have no hope of seeing that. I have traced the login locale processing through /etc/profile

I think Rscript has a problem running files that have mac encodings for newline (^M rather than ^J on linux). If I source the file within R, it works okay: > source('j.R') [1] "MEA_data/sernagor_new/CRX_P7_1.txt" But if I run the file using Rscript on a linux box I get a strange error message: $ Rscript --vanilla j.R " Execution halted The example script j.R is at

Is it safe to call setGeneric twice, assuming some setMethod's for the target function occur in between? By "safe" I mean that all the setMethod's remain in effect, and the 2nd call is, effectively, a no-op. ?setGeneric says nothing explicit about this behavior that I can see. It does say that if there is an existing implicity generic function it will be (re?)used. I also tried

Currently library() and attach() fail to locate an existing '.conflicts.OK' in a package wit name space, unless it is exported. Since there should be little interest in exporting '.conflicts.OK' otherwise, one may argue that those methods should look for '.conflicts.OK' even if it is not exported. If so, a patch for library() is: >svn diff library.R Index: library.R

Hi, from 'Writing R Extensions' [R version 2.11.0 Under development (unstable) (2010-03-16 r51290)] one can read: "The optional `Imports' field lists packages whose name spaces are imported from but which do not need to be attached. [...] Versions can be specified, but will not be checked when the namespace is loaded." Is it a design decision that version specifications
