Hi everybody, does anybody know if R contains error functions like "erf" and "erfc" in S-Plus? Thanks in advance.

Hi, is it possbible to include the Latex-variable \vartheta into a plot (using, for instance, the expression function). Thanks in advace Salvatore

Hi all! Is there a possibility to read Latex-formulas directly into R, e.g. to read c=\frac{a}{b} such that R knows that c<- a/b is meant? I wish to generate some numerical examples of a...

Dear R-"helpers"! May I kindly ask the pure statistics-experts to help me for a purpose which first part is not directly concerned with R. Consider two distribution functions, say f and g. For both, the median is smaller...

Hi all! Consider a sample, x, like this: # x<- matrix(rbind(4,8,0,2, 25,30,5,32), ncol=2) # Weight Income 4 25 8 30 0 5 2 32 Here the "Weight" assigns the weight of each observation...

Hi everybody, on ?plotmath it can be seen that mathematical expressions like a greek letter could not be used for x- and y-axis labels in 'persp' plots. Unfortunately, this is exactly what I want to do: I need an...

An alternative but also higly recommendable way is the use of the psfrag-package in your LaTeX-file. It is furthermore very simple in use. Type plot(1:10, main="test") in your LaTeX-file you insert in your figure...

Hi everybody, I have some troubles by using R with weighted data. It is very easy to obtain the mean of a weighted data set due to the function weighted.mean, but unfortunately, such a function is not available for...

dev.copy2eps works fine, but, however, does anybody know how to rotate the figure? dev.copy2eps(horizontal=F) doesn't work. On Thursday 13 November 2003 15:40, Peter Dalgaard wrote: > Uwe Ligges <ligges at statistik.uni-dortmund.de> writes...

Dear Rama Giorgia, if you are using R under Unix you should call R with R --vsize=600M --nsize=25000k Further, use scan() directly. It works much more better than read.table(). Greetings s. On 3 Jul 2002, at 9...

Dear In-Sun, how to solve your problem depends on the system you are working. If you are starting R via UNIX, you should call R with R --vsize=500M --nsize=20000k (500 and 20000 are only examples) If you...
