Dear R-Users, I am trying to use paste to paste the character ' around a character vector. Paste appears to place spaces (" ") around this. Anyway this can be done without the unintended introduction of space characters ? Please see example below. Many thanks, Tolga > charlist<-c("a","b","c") > lapply(charlist, function (y)

Dear R Users, I would like to get the pdf() command to create graphics in landscape mode, as I am plotting 8 graphs in 2 rows and 4 columns. This is being generated for an a4 printer (so I also use the paper="a4" command). Is there a way I can ask pdf() to generate the document in landscape mode ?

Dear R Users, A bit of a simple question, but I could not find the answer thru google ("sorting lists r cran","how can i sort a list r cran") or RSiteSearch... how can I sort a list ? One imagines something like sort.list would do the job, but that's not the one. > foo<-list(a=10,b=2,c=3) > sort.list(foo) Error in sort.list(foo) : 'x' must be atomic

Dear R Users, How can I send commands to the R GUI from within a R script in Microsoft Windows ? I am trying to get the windows within the R GUI to Tile after I draw a graph.

Dear R Users, I am on Windows XP SP2 platform, using R version 2.7.2 . I was wondering if there is a way to find out, within R, the number of CPU's on my machine ? I would use this information to set the number of nodes in a cluster, depending on the machine. Sys.info() and .Platform do not carry this information. Thanks in advance, Tolga Uzuner Generally, this communication is for

Dear R Users, Is there a package or some functionality in R which returns statistics on "runs" of numbers, i.e. series of numbers with similar qualities in a time series ? For example, the number of +ves,-ves, histograms on cumulations in runs, etc. ?

Dear R-Users, Is there a way to create a matrix of data frames in R ? I am pulling in data frames from a SQL database into R using RODBC. I would like to pull in a sequence of data frames which are indexed across two dimensions, and store each data frame as an element in a matrix. I did try this: names<-c("foo","bar") years<-c("1y","2y")

Dear R Users, I would like the R GUI to display numbers with comma separators, i.e. 1,000,000.00 instead of 1000000 Is there a flag in option() for this behaviour. A google/RSiteSearch has not revealed anything but perhaps I have missed it.

Dear R Users, Is anyone aware of a package which calculates the Yule Kendall resistant (to errors,outliers) measure of skewness ? An easy calculation to perform, but was just wondering if a package exists (as the contents of that package would probably include other cool things I would also be interested). Thanks, Tolga Generally, this communication is for informational purposes only and it

Dear R Users, Was wondering if anyone can give me pointers to functionality in R that can help "clean" a time series ? For example, some kind of package/functionality which identifies potential "errors" and takes some action, such as replacement by some suitable value (carry-forward, average of nearest, what have you) and reporting of errors identified. I did search

Dear R Users, I am attempting to use snow with rmpi. My configuration is: - R Version 2.7.2, rmpi - RMPI 0.5-6 - DeinoMPI 1.1.0 - Windows Xp SP2 I can sucessfully create a cluster and execute simple commands but for some reason, I cannot change the working directory in my nodes. > noclusters<-2 > cl <- makeCluster(noclusters, type = "MPI") 2 slaves are spawned

Dear R-Users, I am looking for a way to get legends placed automagically in an empty spot on a graph. Additional complication comes through my useage of multiple graphs on the same plot through mfrow. Is there a way to achieve this in R ? I have legends for each of the sub-plots. Many thanks in advance, Tolga Generally, this communication is for informational purposes only and it is not

Dear R Users, I am attempting to use the snow package for clustering. Is there a way to identfy, in the environment of each node, a rank for that node and also, the total size of the cluster ? By way of analogy, I am looking for the functions in snow equivalent to mpi.comm.rank() and mpi.comm.size() from RMPI, in case that makes things clearer. Thanks in advance, Tolga Generally, this

Dear R Users, I am looking for a smoothing function with the following characteristics for a time series of data: - at each date, should only use data up to that date (so, right aligned and not centered) - should return a smoothed series of length equal to the original time series: - for a one-day time series, just returns that day - this means the front part of the series will

Dear R Users, How can I create names for lists within a function where the name itself is a function of several variables ? > a<-1 > b<-2 > paste(a,b) [1] "1 2" > foo<-list(paste(a,b)=3) <<<===== DOES NOT WORK Error: unexpected '=' in "foo<-list(paste(a,b)=" > eval(paste(a,b)) [1] "1 2" >

Dear Achim, R Users, What am I doing wrong in this example ? a<-zoo(rnorm(100),order.by=1:100) b<-lag(a) regr<-na.exclude(merge(a,b)) plot(regr) grangertest(regr[,1],regr[,2],3) > a<-zoo(rnorm(100),order.by=1:100) > b<-lag(a) > regr<-na.exclude(merge(a,b)) > plot(regr) > grangertest(regr[,1],regr[,2],3) Error in solve(vc[ovar, ovar]) : subscript out of bounds

Dear R Users, A bit of an elementary question, but somehow, I haven't been able to figure it out. I'd like to changes the column names of a data frame, so I am looking for something like col.names (as in row.names). Could someone please show me how to change the column names of a data frame ?

Dear R Users, I am trying to suppress the information printed by the ecdf function during an assignment. Various alternatives have failed me so far: > a=summary(ecdf(rnorm(100)))["1st Qu."] Empirical CDF: 100 unique values with summary > invisible(a=summary(ecdf(rnorm(100)))["1st Qu."]) Empirical CDF: 100 unique values with summary > (function()

Dear R Users, A recent update on base packages on my R installation has introduced a problem to my code which did not exist before the update. The offending function is rbind, which fails where it was working just fine before the update. I have two zoo objects, foo and bar, indexed by class Date. foo starts from "2007-10-09" and bar from "2007-10-10". I attempt to pad
