Re: [R] convert list int data frame

Hi Luigi, It depends on how you want to put the different elements of my.list into a data.frame. Basically, data.frames are lists, so doing data.frame(my.list) is straigthforward. HTH, Ivan -- Ivan Calandra, PhD University of Reims Champagne-Ardenne GEGENAA - EA 3795 CREA - 2 esplanade

Re: [R] Boolean expression

Hi Jue, The character sequence "<-" is preferentially interpreted as "assign the value on the right to the name on the left". You can use parentheses to force the unary minus to be interpreted: if(a<(-1)) or you can just break the sequence with a space: if(a< -1) One less character, but

Hello, R subtracts the _column_ vector 'mean' to X (column by column). Apparently you want the transpose, or think 'mean' is a row vector. Try instead t(t(X) - mean) And use another name for 'mean', it already is the name of a function. Hope it helps, Rui Barradas Em 14-09-2015 16:11,
