Re: [R] xtable prcomp

Hi, The "xtable" method for "summary.prcomp" is just creating a table of the "importance" values. So you can get the same table for just a few of the PCs by subscripting the importance values: xtable(mySummary$importance[,1:2],digits=4) Best, Charlie -Original Message- From: r-he

Re: [R] predict.lm, matrix in formula and newdata

Hi Stephan, You'll get the expected result if you pass a data.frame to the lm() function when fitting the model. > yy <- runif(4) > XX <- matrix(runif(8),ncol=2) > df <- data.frame(y=yy, XX) > df yX1X2 1 0.52889284 0.8055476 0.6670006 2 0.09989951 0.2498907 0.8867955 3

Re: [R] replacing values in a vector
