Dear all, I am facing a strange problem with text files formats. I am currently using a C++ code named voro++ (http://math.lbl.gov/voro++/). This code accepts text files with four columns: <id> <x> <y> <z> where id is an identification number and x,y,z are the coordinates of a point in a 3D space. The input file, name it myfile_cpp.txt, is generated by another C++ code

R 2.1.1 Win 2k Would someone suggest a method (or methods) that can be used to determine ntile cutpoints of a vector, i.e. to determine values that can be used to divide a vector into thirds such as 0-33 centile, 34-66 centile, 67-100 centile. If for example I had a vector: 1,2,3,4,5,6,7,8,9 and wanted to divide the vector into thirds I would have cut-points of 3, and 6. Thanks, John John

Hello comunity, I'm trying to find a similar function as decile of SPSS, NTILES (10) some of you know about that, I will appreciate your help in advance.

...ot;|". The number of input filenames changes (minimum 1, maximum n) wrkdr <- "H:\\akk_temp\\Modis\\MOD09" dates is a data.frame where each row is a date and each column is a Modis-image (the name of it) I did this as following: paste('INPUT_FILENAMES = ', for(g in 1:(ntiles-1)) {paste(wrkdr,'\\',dates[i,g+1],'|',sep='')} , for(g in ntiles){ paste(wrkdr,'\\',dates[i,g+1],sep='') } ,sep='') ....and this did work (in an other "wrkdr" and other "dates") but after changing, "for" gave no more o...
