Hello everyone, I have the following matrix ? ? ? ? ? ? [,1] ? ? ? ? ?[,2] ? ? ? ? ?[,3] ? ? ? ? [,4] ?[1,] ?0.002809706 ?0.0063856960 ?0.0063856960 ?0.011749681 ?[2,] ?0.004893124 ?0.0023118418 -0.0005122951 -0.014646465 ?[3,] ?0.003547897 ?0.0063355297 ?0.0030410542 ?0.011403953 ?[4,] ?0.004838299 -0.0040383645 -0.0090406831 -0.011027569 ?[5,] ?0.035648755 ?0.0334815590 ?0.0380977404 ?0.059817597 I want to apply a function on each column varying the first parameter of the function. If I do it on one column only with apply it works perfectly as follow: apply(column1, 1, myfunction, parameter1= ..., parameter2=...) But when I try to do it on each column without even varying the parameter it doesn't work: apply(matrix, 2, apply, MARGIN = 1, Fun ?= myfunction, parameter1 =..., parameter2=...) I get the following error: Error in FUN(newX[, i], ...) : ?unused argument(s) (2, function (X, MARGIN, FUN, ...) Does someone know how to solve this? and is there a way to send a vector of parameter1 instead of a scalar? thank you ----- Anna Lippel -- View this message in context: http://n4.nabble.com/Applying-a-function-on-each-columns-of-a-matrix-tp1415660p1415660.html Sent from the R help mailing list archive at Nabble.com.
