also to the authors of the function, Peter Dalgaard and prof Ripley (I suspect prof Ripley is responsible for the matrix improvment ?). Many thanks also to all the contributors to the last version of this wonderful software. Vincent __ R-help

[R] matrix subset

but in fact I would appreciate m1 to be also a matrix, and thus would like to get : m1 [,1] [,2] [,3] [,4] [2,]258 11 [3,]369 12 ... but I don't find how to do ? (probably it is very simple ! double shame.). Thanks for any hint or pointer. Vincent

Re: [R] matrix subset

. They are only generally used if you wish to place more than one R statement on a single line. I'm an old C programmer ... and it's an old (good) behavior. Without semicolons at the end of lines I feel naked like a worm in the desert. (I'll keep them). Thanks for your kind help. Vincent

Re: [R] how to write and read an array ?

Francisco J. Zagmutt a écrit : check ?dput and ?dget Thanks for the answer. dput and dget work well (even if the internal data writing is not as directly readable as with write.table()) (When I'll be grown-up with R, I'll write a write.3dtable() function.) Thanks. Vincent

[R] numeric index of a matrix column name ?

: the numeric index of the column colnameindex = function(M , colname0) { colsnames = names(M[1,]); theindex = which(colsnames==colname0); return(theindex); } Thanks Vincent __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo

Re: [R] numeric index of a matrix column name ?

Dimitris Rizopoulos a écrit : probably you need match(colname0, colnames(M)) I hope it helps. Best, Dimitris yes. (why do simple ...) Thanks Dimitris. Have a good we. Vincent __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman
