Dear users, is anybody of you aware of a R command to perform laplace transform or even its inversion? Thank you very much. Luca

Hello, I am trying to use 'R' for K-means simulatio, could you please advise me how I can read my data into a two dimesional array? Or is there any method which directly reads the excell file? Please let me know asap. Regards Skanda Kallur Cogito, Ergo Sum! Rene Descartes

Dear R experts, format(12345678, digits = 2) gives [1] "1.2e+07" while format(1234567, digits = 2) gives [1] "1234567" but I'd like the last number to be represented as "1.2e+06" string too. Where am I wrong? Thanks, Timur.

Dear R users, I'm having trouble using aggregate() and would greatly appreciate your advice. I am using R 1.5.1 on Windows 2000. I want to call my function in the following way extract.data(x=dat[, "Age", "Year"]) where extract.data() uses aggregate() to count the number of cases for each combination of "Age" and "Year". I've defined

Dear R-gurus: How do I overlay 2 plots in the same frame in R? Or, if I have a histogram, and I want to plot a function in the same frame - how do I do it?

Hi, I am running a loop to plot multiple plots. In s-plus, it shows multiple pages in the graphic window to allow checking on each plot. but in R, the next plot always overwrite the previous one, so i can only have the last plot produced, is there a way to have multiple pages in the graphic window just like S-plus does? Thanks

Hi, Suppose I have a multidimensional array: tmp <- array(1:8, c(2,2,2)) is there a function out there that, given a one-dimensional array index, will return the separate indices for each array dimension? for instance, tmp[8] is equivalent to tmp[2,2,2]. I'd like to derive the vector (2,2,2) from the index 8. thanks, Brad Buchsbaum

Subject: activity of CPU used by R X-Mailer: VM 7.00 under 21.4 (patch 6) "Common Lisp" XEmacs Lucid Reply-To: fjmolina at lbl.gov FCC: ~/mail/sent My R processes never use more than 50% of my CPU activity.

I have written the following function to calculate the weighted mean difference for univariate data (see http://www.xycoon.com/gini_mean_difference.htm for a related formula). Unsurprisingly, the function is slow (compared to sd or mad) for long vectors. I wonder if there's a way to make the function faster, short of creating an external C function. Thanks very much for your advice. gmd

I am participating in a project in the university, and appeared a doubt: if can I call one function from R as "solve" from C code. The intention of the research is to create a DLL. Is it possible and where can I find an example?

Hey, All Now I have a data set which is n-dimensional. And want to plot the Scatter Plot Matrix which is n by n. Does R have such function to achieve this? Thanks for your point. Fred

I am brand new to R and would like to know if there is a way to be able to create, save and retrieve a program in R like a script object in S-Plus. I am just not sure how to do this. I'm sure there are many ways to do this ranging from simple to complex, but the simplest way would be best for me. Thanks, in advance... __________________________________________________ Y!

Dear List Members I'm using R to create a trellis plot using the library of Pinheiro & Bates (trellis graph for grouped data). Here is my question: How can I change the format of the axis (x or y) in terms of the number decimal points that should appear on the plot? In other words, I have that for a set of plots in the y-axis the values appear as 0.2,0.3, etc and for another set they

Hi! I am a relatively new user of R and I use it to prepare my dissertation. I have come to some very usefull and specific libraries written for S-PLUS 4 and would like to use them in R. Is that possible? I just found out that one of these libraries has already been transfered to R, while 3 others have not. For the matter of beeing more exact I''m interested in the dealing with missing
