Re: [R] Need help to print matrix with element and position
Hello, With no loops: cbind( row = c(t(row(mat_1))), col = c(t(col(mat_1))), mat_1 = as.numeric(t(mat_1)) ) If the matrix entries are not numeric, use cbind.data.frame. This will keep the row and column numbers as numbers, the default cbind method would coerce them to the class of mat_1's elements. cbind.data.frame( row = c(t(row(mat_1))), col = c(t(col(mat_1))), mat_1 = c(t(mat_1)) ) Hope this helps, Rui Barradas Às 09:19 de 28/10/21, Anas Jamshed escreveu: I create a matrix of size 3x3 called mat_1 and then I want to iterate over all the values one by one and print the element as well as the position in the matrix: My code is : mat_1= matrix( c('1','2','3','4','5','6','7','8','9'), nrow = 3, ncol = 3,byrow = TRUE) mat_1 # Loop over my_matrix for(row in 1:nrow(mat_1)) { for(col in 1:ncol(mat_1)) { print(mat_1[row, col]) } } But I don't know how to print elements and positions as well of this matrix?

Re: [R] Need help to print matrix with element and position
where should I place cat(row,col,mat_1[row,col],"\n")?

Hi Anas, How about: cat(row,col,mat_1[row,col],"\n") Jim On Thu, Oct 28, 2021 at 7:19 PM Anas Jamshed wrote: > > I create a matrix of size 3x3 called mat_1 and then I want to iterate over > all the values one by one and print the element as well as the position in > the matrix: > > My code is : > > mat_1= matrix( c('1','2','3','4','5','6','7','8','9'), nrow = 3, ncol = > 3,byrow = TRUE) > mat_1 > # Loop over my_matrix > for(row in 1:nrow(mat_1)) { > for(col in 1:ncol(mat_1)) { > print(mat_1[row, col]) > } > } > > But I don't know how to print elements and positions as well of this matrix? > > [[alternative HTML version deleted]] > > __ > R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see > 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. __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
[R] Need help to print matrix with element and position
I create a matrix of size 3x3 called mat_1 and then I want to iterate over all the values one by one and print the element as well as the position in the matrix: My code is : mat_1= matrix( c('1','2','3','4','5','6','7','8','9'), nrow = 3, ncol = 3,byrow = TRUE) mat_1 # Loop over my_matrix for(row in 1:nrow(mat_1)) { for(col in 1:ncol(mat_1)) { print(mat_1[row, col]) } } But I don't know how to print elements and positions as well of this matrix?
