Z aware interpolation
...rpolation (i mean the one which takes into consideration only x and y coordinates) so i can try to modify it to take into consideration z values as well. I am not sure it will work, or i can do it - but it worth a try - of course if this is not already done.

Hi, I would like to write a little automatic routine in R, but i am a too much of a beginner for that. I will appreciate any help regarding this particular problem. Let?s suppose I have a data.frame with j columns (from 1 to n) and i rows (from 1 to p).

Meanwhile i have this new question: suppose i have a data.frame with x and y columns and 10 rows, 1 to 10. I also have a variable m (or an array if you like) with 5

Does R runs on IRIX 6.5 platforms?
Hi, I am trying to do a bayesian modelling and my Windows PC seems not to have enough memory to do it. So now i would like to run GeoR on an IRIX 6.5 platform (UNIX related as i understood). Do you know if R is compatible with this type of platform? I am not allowed to try it until i have an answer to that. Thank you so much, Monica

log Y scales for parplot
Hi, I am doing a barplot, and the fist bar is very big (high values) and the rest of the bars are quite small (small values). So - is there any way to make the Y scale logarithmic so that i have a wider distance from 0 to 50 for example than for 50 to 100, and so on? Thanks in advance for any help, Monica

basics: how do you sort a table?
Hi, This may be a very basic question but it seems i cannot figure it out does not matter what. how do you sort a table (ascending or descending) after the values in one particular column? I want to do something like the sort function in Xcel. Also, is there any other plot function that accepts log for y axes like the parplot2() from gregmisc? Thanks for the tip Marc about barplot2. very
