say i have a column of data like this... 2 3 4 2 1 6 6 4 7 and i want it in three columns like this 226 314 467 ...so i can make a contour plot.

Hi french, Here is a suggestion: x <- c(2, 3, 4, 2, 1, 6, 6, 4, 7) matrix(x, ncol = 3) # [,1] [,2] [,3] # [1,] 2 2 6 # [2,] 3 1 4 # [3,] 4 6 7 with x the column of data you have.

Tena koe ?matrix The exact syntax will depend on the class of your 'column of data'. If it is a dataframe, for example, then try matrix(yourData[,1], 3, 3) HTH ...

Hint 1: A matrix can use characters or numerics
Hint 2: "" can be considered as a character.
