[R] inline function in apply

I've been trying to filling in the missing variables in a matrix with the mean from the column they are in. So the following code does this just fine. #3X3 matrix where the middle number is missing. data=matrix(c(1:4,NA,6:9), 3, 3) #replace missing values in an vector with the mean of the vect

[R] Filtering matrices

I'm using the rcorr function from the Hmisc library to get pair-wise correlations from a set of observations for a set of attributes. This returns 3 matrices; one of correlations, one of the number of observations seen for each pair and the final of the P values for each correlation seen. >From

[R] Show representation of a data structure

I'm currently working with some large complex data structures eg list of lists of data_frames containing lots more variables and lists etc. Sometimes, I'd like to be able to bring up a simple representation of the structure I'm working with, minus all of the values it contains (so simply printin

[R] Obtaining average ranking from matrix of frequencies

I have a small matrix where the columns represents a ranking and the values are the number of times each ranking was obtained eg 1 2 3 x 1 2 0 y 0 1 2 z 2 0 1 I'd like to be able to return an average of the ranking obtained average x 1.67 y 2.67 z 1.67 Whats the nicest
