Hi everybody, let us assume i have the following matrixX and vectorY matrixX <- runif(100) dim(matrixX) <- c(10,10) vectorY <- as.matrix(as.character(seq(1,10)))
if I define: subsample<-c("2") i can extract the rows from matriX based on the elements in vectorY which are listed in subsample matrixX[vectorY==subsample] if I define subsample with more than 1 element, such as: subsample=c("2", "3") how can i extract the rows from matriX based on the elements in vectorY which are listed in subsample? many thanks Roberto Furlan University of Turin -- ---------------------------------------- La mia Cartella di Posta in Arrivo รจ protetta da SPAMfighter 259 messaggi contenenti spam sono stati bloccati con successo.
