Hi, I am using R 2.3.0 and my .First() file has the following line which causes a warning: attach(what="c:/r/jmb/.RData", pos=3) I get the following message after .First() is loaded: During startup - Warning message: use of NULL environment is deprecated Is there a simple fix that will eliminate this warning message? Thanks. J. Breiwick

Hi, all. I was trying to build my R package with R 2.15.1 32bit and win7. I basically follow the routine in Steven Mosher's blog http://stevemosher.wordpress.com/step-10-build/ After I fixed the path, and built the skeleton of the package, I started command prompt and used the following commands in building my package Rcmd check myPackageName Rcmd build myPackageName Rcmd check

All, I have used package.skeleton, edited the .Rd files and the DESCRIPTON file. In one of my package functions I am using RODBC so I have a line of code that reads: require(RODBC). In my DESCRIPTION file I have the following relevant line: Depends: R (>= 2.9.0), RODBC However, when I do a check (Rcmd check my_package_name) I get this warning: * checking for unstated dependencies in R code

Hello, I have a workspace that contains a number of functions I want to put in a library. Under R 1.9.0 I did this fairly easily by putting them in a R folder, creating a DESCRIPTION & TITLE file etc. I could then load my library successfully. Under R 2.0.0 this simple process apparently no longer works. I have used package.skeleton() and have run R CMD INSTALL pkgname but still get various

I am experiencing an issue combining bitcode files for the purpose of generating the combined bitcodes as a single bitcode file. I would like to have any pointers to help me debug this or maybe it has been seen before and a fix is either being worked on or is done. I am using the Xcode 9.0 compiler. I believe the Swift code is 3.x. I have reproduced this using the tot llvm-link. The input

Dear R-users, It is my understanding that cat(shQuote(a.string)) should print the origintal a.string. Is this right? I am not sure cat() correctly prints strings which are generated by triple-shQuote(): > shQuote(shQuote("a")) [1] "\"\\\"a\\\"\"" > cat(shQuote(shQuote(shQuote("a"))), '\n')

Hi all, I would like to know if there is any way to evaluate the values in `Sys.setenv` before setting the environment variables. For example, if we want to add a path to the environment variable `PATH`, we can do this in a terminal ``` > export PATH=~/mypath:$PATH > echo $PATH /Users/jeff/mypath:... ``` However, this style of assignment is not allowed in `Sys.setenv`, it treats its

Dear R users, this is a question for R version 1.2.0 under Windows NT 4.0, regarding the documentation of ones own functions. I have ceated a private library for my functions, which works all very well, apart from that I am not able to create appropriate help files. For illustration, here is a simple example of where I'm stuck: > # first, create a simple function f1: > f1 <-

Linux Red Hat 6.x Using name = <mypath>/%U in recycle.conf is ok, while using name = <mypath>/%u produces a dir <mypath>/%u/deleted.item I need to use %u since %U is before smbusers mapping. Do you get the same behavior? Thanks -- giulioo@pobox.com

R Community, I often am in need of viewing the reference manuals of packages and do not have Internet access. I have used the code: path <- find.package('tm') system(paste(shQuote(file.path(R.home("bin"), "R")),"CMD", "Rd2pdf",shQuote(path))) someone kindly provided from this help list to generate the manuals from the latex files. This

Dear All, I want to compare formulas resulting from using stepAIC() on glm() objects. I have 2 different formulas, say F1 and F2, which consist of about 10 factors (Y~A+B+C+...) but one has an interaction term (A:B) while the other doesn't. But when I perform F1==F2 it comes back as TRUE. Is there a proper way to compare formulas? ------------------------------------------- Jeffrey M

Hello, I want to plot 3 boxplots [ par(mfrow=c(3,1)) ] but the first one has 8 groups, the 2nd has 7 and the third has 6. But I the groups to line up: 1 2 3 4 5 6 7 8 2 3 4 5 6 7 8 3 4 5 6 7 8 where the numbers actually refer to years. I suspect I have to manipulate the function bxp(). Is there a relatively simple way to do this? Thanks for any help. Jeff Breiwick NMFS, Seattle

Hi again! While investigating the bug report [*] I found out that on unix, system2 does not quote its `stdin` argument while preparing the command line to launch. It does shQuote the `stdout` and `stderr` arguments, and also the `f <- tmpfile()` variable (which is used if `input` argument is provided), which seems to set a precedent. On Windows, stdin, stdout, and stderr are handled

Dear friends of R, I want to produce a pdf file with the contents of a matrix. I employ the latex command in combination with dvi, both contained in the Hmisc package. It seems to me that the function does not correctly set the directory. > tbl.loc <- matrix(1:4, nc=2) > latex.obj <- latex(tbl.loc) > dvi(latex.obj) warning: extra args ignored after 'cd' H:\PROJECTS\data

Hi, I am using ruby 1.9.2 and rails 3 for my application. I have written a bash script which I want to run in cron. If I directly run the bash file it runs.

Estimados Hace unos días envié un correo porque tenía problemas para guardar los gráficos en el disco rígido, utilizando R server 9, comentaba que el código antes funcionaba pero que tenía fallas. No encuentro mi mensaje en la lista para continuar el hilo, encontré el problema, no lo comprendo del todo pero cambiando jpg por png funciona, aparentemente hay un inconveniente para guardar en jpg.
