To replace particular values in a matrix we can use the following command.
matrix[x,y] = value But what to do if I have a list of +- 1,000,000 values and associated x,y values. Is there an efficient way to replace my matrix with those values. My first idea was to replace x, y and values by vectors.......but that doesn't work. Value in this case can't be a vector :(. It results in a wrong replacement. It takes the last value of the matrix......... -- View this message in context: http://www.nabble.com/Replace-values-matrix-tp20562113p20562113.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
