Hi! I have a test file with all special characters of hungarian language on a windows share: ??????????????????.txt (I hope Your mailer wiill show them correctly :-)) When I use smbclient to connect to share, I see correct characters, I can get the file to local disk and ls shows the correct name too. When I try to mount with smbmount the closest result I produced was: ?I???AuUoO?U?????O.txt cp

Hi, I've built and installed the openssl-0.9.1c package but openssh-2.1.1p1 configure can't apparently 'see' the package. I've tried adding the install directory to LD_LIBRARY_PATH, using CFLAGS, LDFLAGS, LIBS etc. The 'missing' rand.h is present n the included path shown in the config.log output below. What am I missing? Any help would be very much appreciated.

Hi, just curious, but does anyone know the source/reason of observing the following error on OSX but not on WinXP and Linux? I've tried with a few different versions of R (v2.5.1, v2.6.1, v2.6.2, v2.7.0devel). The locale does not seem to affect the error, i.e. I've tested a few different and it is still only OSX that gives the error but not the other two. > regexpr("[a-Z]",

Hi All R guru's, A couple of simple questions which I cannot find answers to in "an introduction to R" or in the reference manuals. I am running R on Win95, and have plotted up quite a nice box and whisker plot: char<-read.table("n:/reddinm/grifpr~1/survey/char.txt") attach(char) boxplot(Al,Fe,OC,pH, range=0,xaxis=FALSE, ylab="Proportion of Unirigated

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm generating a symmetric correlation matrix using a data matrix as input: mat <- cor(data.mat) My question is: Is there a more memory efficient way to store this data? For instance, since: all(mat == t(mat)) every value is duplicated, and I should be able to almost half the memory usage for large matrices. Any thoughts/comments? Cheers,

Can anyone point me in the right direction for decompressing text files that are compressed as tar.gz or zip files?

I have 2 sets of data which defines the start and end of date/time periods. I want to be able to obtain the following: 1) The intersect of those 2 sets of date/time ranges i.e. return start/end date/time ranges where both sets overlap 2) The union of those 2 sets of date/time ranges i.e. return the start/end date/time ranges which are in 1 or both sets Is there anything that is currently able

Dear R users, I have recently started using R. I need to execute a FORTRAN file within R. Does it allow to call executable (or FORTRAN code) file within R ? Thank you very much in advance.

I have a data.frame obj with 5 columns whose colnames match the fields in my "contact" table. The only other field my MySQL table has is an id field which is the PK and is set to auto increment. I'd like to load this data.frame using something like: dbWriteTable(con, "contact", dat, append=TRUE) However, I get this error: Error in mysqlExecStatement(conn, statement,

Are there any particular licences under which R packages must be released or is it the discretion of the author? The same question if the package is to be destined for CRAN?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a rectangular matrix of size 920 by 85. I'd like to coerce it into a square matrix such that all row/col names are present in the new matrix and the additional values are zero. As an example: A B C D A 1 2 3 4 E 5 6 7 8 F 9 10 11 12 Would be coerced to: A B C D E F A 1 2 3 4 5 9 B 2 0 0 0 6 10 C 3 0 0

Dear lists, I want to construct a loop in R, but don't know how to do it. I can do it in SAS, but I prefer in R (which I am hoping I will off SAS for good soon). Could anyone help me to convert the SAS codes to equivalent R codes. Basically, the following codes were written to establish the sire gametes or phases for daughter design for one markers two alleles. Here are the SAS code: do

Hi All, Anybody know how to make R emit base64 encoded text in some way that perl can grab it, instead of planting a file on your harddrive when calling JPEG or PNG?
