similar to: R: possibility for sth. like parameter passing by reference?

Dear all, is there an easy way to know at which position in the source code browser() (or stop()) was called? This seems to be important for me when I try to debug a program (e.g. using options(error=quote(dump.frames()))) traceback() returns some information, but I miss something like a line number, e.g. "stopped at line 999 in foo.R".

Hi List, is sth. like the following possible: legend(x,y,c("A","B","C"), lty=list(1,"42","11")) ? Or: is there a possibility to define a solid line using the "string" mode for lty?

Dear Rs, quite often in I had segmentation faults of the following kind: Error in brf.infobase(nn, Pc, knams = knams, plot = plot, dev = dev, quiet = quiet, : unused argument(s) (df ...)

Dear all, after building the R-1.1.1 from source on our alpha everything seems to work, but locfit still hangs... I installed locfit with install.packages(...), the installation process went fine, but calling locfit() blocks the R environment. Has anybody got an idea howto get to the roots of this problem? Thanks M. Eger -- +------------------------------------------------------- | Marcus

Dear R'ers, when I e.g. install the integrate2.2-2 package under R1.1.1 (debian2.2) atlas is linked into the library: Installing package `integrate' ... libs gcc -shared -lc -shared -o /usr/lib/R/library/integrate/libs/integrate.so adapt.o adapt_callback.o bsrl.o flfm.o nxprt.o symrl.o wht.o -L/usr/local/lib -lf77blas -lcblas -latlas -lg2c -lm -L/usr/lib/gcc-lib/i386-linux/2.95.2

Dear all, usually I work under linux, but I tried to install R-1.1.1 on our alpha's which worked well.

I have some slight problems getting R to run smoothly on our alpha...

Dear R-ers, somehow it is not possible to increase nsize to more than 20000k.

What is the best way (if possible) to pass the name of a workspace file to R when it starts so it is loaded instead of .RData ? I would like to know this for Linux and windows version. For windows I would like to associate the .RData extension so doubleclicking the file starts R and loads it. Thanks -- Victor Moreno V.Moreno at ico.scs.es Servei

Hi all, I've got this graphics question which really should be easy. I want to shade an area between bounds under a curve. A suitable beginning seems to be the following: > plot(dnorm,-4,4) > segments(-4,0,4,0) > segments(-2,0,-2,dnorm(-2)) > segments(2,0,2,dnorm(2)) It is the area between -2 and 2 which I want to shade (or something similar). Hints anyone? Robert

Is there a missing value constant defined for R_xlen_t, cf. NA_INTEGER (== R_NaInt == INT_MIN) for int(eger)? If not, is it correct to assume that missing values should be taken care/tested for before coercing from int or double? Thank you, Henrik

I've recently installed Debian/GNU Linux 2.2.
