xyplot problem
Hi all, I am trying to produce some panels with dots in an X/Y plane where the diameter of the dots indicates a Z value (like e.g. earthquake maps where dot sizes indicate magnitudes and X/Y the location). This works fine with xyplot, e.g.: xyplot(1:3~1:3,cex=1:3,pch=16) However, when I do this with a panel variable, e.g.: x<-rep(1:3,5) y <- rep(1:3,5) sz <- rep(1:5,each=3) grp

nlrob problem
Dear all, I am not sure if this mail is for R-help or should be sent to R-devel instead, and therefore post to both. While using nlrob from package 'robustbase', I ran into the following problem: For psi-functions that can become zero (e.g. psi.bisquare), weights in the internal call to nls can become zero. Example: d <- data.frame(x=1:5,y=c(2,3,5,10,9)) d.nlrob <-

Error compiling on HP-UX
Dear all, I hope this is the right mailing list for my question -- I felt that this was too technical for R-help. I am trying to compile R-2.4.0 on a HP-UX system: ./configure MAKE=gmake --prefix=$HOME --without-x --without-tcltk --disable-R-profiling --without-readline --disable-multibyte R is now configured for ia64-hp-hpux11.23 Source directory: .

New R function is.nana = is.na & !is.nan
Hello R-devel, Best wishes in the new year. I am writing to kindly request new R function so NA_real_ can be more easily detected. Currently if one wants to test for NA_real_ (but not NaN) then extra work has to be done: `is.na(x) & !is.nan(x)` Required functionality is already at C level so to address my request there is not that much to do. Kevin Ushey made a nice summary of current R C api

New R function is.nana = is.na & !is.nan
"nana" is meant to express "NA, really NA". Your suggestion sounds good.

Object.isNumber() returns true on NaN??
Hi, Object.isNumber() returns true on NaN. I don''t think that''s true.... NaN is Not a Number so it''s not a number... right? By the way, I''m using Prototype 1.6.0.2.

noncommutative addition: NA+NaN != NaN+NA

simple loop iteration

max and pmax of NA and NaN
Dear R users, is the following OK? > max(NA, NaN) [1] NA > max(NaN, NA) [1] NA > pmax(NaN, NA) [1] NA > pmax(NA, NaN) [1] NaN ...or is it a bug? Documentation says that NA has a higher priority over NaN. Best regards, Michal Burda [[alternative HTML version deleted]]

base::mean not consistent about NA/NaN
Hi, base::mean is not consistent in terms of handling NA/NaN. Mean should not depend on order of its arguments while currently it is. mean(c(NA, NaN)) #[1] NA mean(c(NaN, NA)) #[1] NaN I created issue so in case of no replies here status of it can be looked up at: https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17441 Best, Jan [[alternative HTML version deleted]]

NA_real_ <op> NaN -> NA or NaN, should we care?
On Linux when I compile R 2.10.0(devel) (src/main/arithmetic.c in particular) with gcc 3.4.5 using the flags -g -O2 I get noncommutative behavior when adding NA and NaN: > NA_real_ + NaN [1] NaN > NaN + NA_real_ [1] NA If I compile src/main/arithmetic.c without optimization (just -g) then both of those return NA. On Windows, using a precompiled R 2.8.1 from CRAN I get NA for

NaN, Inf to NA
Hi, I want to recode all Inf and NaN values to NA, but I;m surprised to see the result of the following code. Could anybody enlighten me about this? > df <- data.frame(a=c(NA, NaN, Inf, 1:3)) > df[is.infinite(df) | is.nan(df)] <- NA > df a 1 NA 2 NaN 3 Inf 4 1 5 2 6 3 > Thanks! Cheers!! Albert-Jan

Benefit of treating NA and NaN differently for numerics
Hello, I notice in main/arithmetic.c, that NA and NaN are encoded differently(since every numeric NA comes from R_NaReal which is defined via ValueOfNA) . What is the benefit of treating these two differently? Why can't NA be a synonym for NaN? Thank you Saptarshi (R-2.9)

NA and NaN in function identical
The help page for function identical says: 'identical' sees 'NaN' as different from 'as.double(NA)', but all 'NaN's are equal (and all 'NA' of the same type are equal). However, we have x <- NaN y <- as.double(NA) x # [1] NaN y # [1] NA identical(x,y) # [1] TRUE In my opinion, NaN and as.double(NA) should be distinguished as the

max and pmax of NA and NaN
Extremes.Rd, that documents 'max' and 'pmax', has this in "Details" section, in the paragraph before the last. By definition the min/max of a numeric vector containing an NaN is NaN, except that the min/max of any vector containing an NA is NA even if it also contains an NaN. ------------------ >>>>> Michal Burda <michal.burda at centrum.cz>

Should as.complex(NaN) -> NA?
I'm having trouble grokking complex NaN's. This first set examples using complex(re=NaN,im=NaN) give what I expect > Re(complex(re=NaN, im=NaN)) [1] NaN > Im(complex(re=NaN, im=NaN)) [1] NaN > Arg(complex(re=NaN, im=NaN)) [1] NaN > Mod(complex(re=NaN, im=NaN)) [1] NaN > abs(complex(re=NaN, im=NaN)) [1] NaN and so do the following > Re(complex(re=1,

NaN/NA and sprintf double format
With a (late prerelease of) 1.5.0 on Windows, using sprintf on NaN yields garbage when the number of decimal is specified while it works fine for NA: > sprintf("%.2f", NA) [1] "0.00" > sprintf("%.2f", NaN) [1] "-1.#J" Not specifying the decimal precision lets both print garbage: > sprintf("%f", NaN) [1] "-1.#IND00" >

Restore a node in a replicating Gluster setup after data loss
Hi We have a Replica 2 + Arbiter Gluster setup with 3 nodes Server1, Server2 and Server3 where Server3 is the Arbiter node. There are several Gluster volumes ontop of that setup.

how to remove NA/NaN/Inf in a matrix??
Hi all.. I'm very new R, and i'm analyzing microarray data using Bioconductor.. Recently i was given microarray data to analyze. The problem is whenever i run MAS5 presence calls algorithm, it throws an error saying NA/NaN/Inf in foreign function. How do i remove such NA/NaN/Inf's ?? I tried na.omit(dataframe) but stil problem exists. dimension of matrix (data) is 35556 7. >
