lpad

Syntax

lpad(str, length, [pattern])

Arguments

str is a string scalar or vector. It is the string to pad characters to (the left-hand side).

length is a positive integer indicating the number of characters to return. If length is smaller than the length of str, the lpad function will truncate str to the size of length.

pattern is a string scalar. It is the string that will be padded to the left-hand side of str. If it is unspecified, the lpad function will pad spaces to the left-side of str.

Details

Pad the left-side of a string with a specific set of characters.

Examples

$ lpad("Hello",2);
He

$ lpad(`Hello, 10);

$ lpad(`Hello, 12, `0);
0000000Hello
