Hi, You may try: op <- options(digits=12) r1 <- 4; c1 <- 4 A <- matrix(scan("file1.txt",n=r1*c1),r1,c1,byrow=TRUE)
options(op) #reset A.K. Dear all, I’m using 'scan' function to import data into a matrix from a .txt file. The data are numbers with 12 significant digits (e.g. 471773.309872). When I give the command: A <- matrix(scan(file_name, n=r*c), r, c, byrow=TRUE) numbers are stored in the matrix with only 7 significant digits (e.g. 471773.3). How can I increase the number of significant digits? Thank you for your reply.
