[R] printing with bothe print and cat...

[Ebert,Timothy Aaron]

Here is an alternative without for loops

n_rows <- 5
n_cols <- 5
p_df <- data.frame(matrix( rep(1:n_rows, n_cols), nrow=n_rows, byrow=TRUE), line_n=1:n_rows)
print(p_df)


If n_rows always equals n_cols then you could combine the first two lines

n_rows <- n_cols <- 5
p_df <- data.frame(matrix( rep(1:n_rows, n_cols), nrow=n_rows, byrow=TRUE), line_n=1:n_rows)
n_cols <- n_cols+1
print(p_df)

You might also notice that as.numeric(rownames(p_df)) returns the same values as line_n.

Here is an alternative that makes a dataframe and then prints the dataframe.
n_rows <- 5
n_cols <- 5
p_mat<-matrix(0,nrow=n_rows,ncol=n_cols)
for(i in 1:n_rows) {
  for(j in 1:n_cols){
    p_mat[i,j]<-(j)
  }
}
p_df <- data.frame(p_mat,1:n_rows)
print(p_df)

Dear David,
                    THe code given was a reprex, and unfortunately, I cannot skip the for loops: Its a very big  web scraping code. Any alternative?

Many thanks in advance...

Yours sincrely,
AKSHAY M KULKARNI

Skip the for loops:

cat(paste( seq(1:5), “    “, 1:5) )
