I have what R seems to consider a very large dataset, a 12MB text file of lat,long,and height values, 130,000 rows to be exact.

....01, 57.34, 20, 1.08, 1 and so forth. I have been struggeling with the split, length and rank commands in R, but can't seem to figure out how to "attach" a new column (or make a new dataset) that has a colums of ranks, or how to calculate the rank. Thanks for any help.

...piling/performance between the Intel Xeon architecture vs AMD 64? Are there pure physical limitations of 64 BIT R that would make intalling it on a grid (http://www.ncsu.edu/itd/hpc/Hardware/Hardware.php) a wasted effort? We have the memory and drive space to do this.

Hi I'm currently using dovecot 2.0 with squat fts which does a nice job. However I'm thinking about upgrading to dovecot 2.1 and the wiki isn't clear about which fts can or should be used with it. Is squat support dead ? As the wiki mentions that the config syntax is obsolete, I'm not sure if squat is obsolete also ? If not, what is the new syntax ? But in the case squat is

I'm trying to calculate a cumulative area distribution (graph) of drainage areas. This is defined as P(A > A*). Simple in principle. I can do this in excel, with "COUNTIF", which will count the number of cells in the row "area" that have area A, then determine, for each cell in the row "area, how many cells exceede that area, then dividing that number by the total

Dear R users, I'm trying to write a small function in order to compute empirical cumulative density function.All seems to work but when I try to plot the function, I always get error messages. This is the function I use mecdf<-function(u,v,z) { u=sort(u) v=sort(v) n=length(u) nb=0 for (i in seq(1,n)) { if (u[i]<z & v[i]<z) { nb<-nb+1 } } nb=nb/n

Dear R friends My goal is to eliminate this specific group(1) if the # of NAs in this group greater than 50%(specifically say greater than 3). Would you please show me how to do it. I have a sample data as following: Thanks a lot. Kevin Lin y group f1 f2 f3 30 NA 1 1 1 1 27 NA 1 1 2 2 48 NA 1 2 1 2 40 -0.6066416 1 2 2 1 24

Hi Is dovecot dsync considered an alternative to offlineimap (or others) when both distant and local are IMAP dovecot servers ? I used offlineimap for this, but somehow offlineimap got messed up (more than once, but without me able to explain how it happened). So I'm considering dsync for this purpose... Thanks! -- erik
