pad {emulator} | R Documentation |
Places zeroes to the left of a string. If the string
consists only of digits 0-9, pad()
does not change the value of
the string if interpreted as a numeric.
pad(x,len,padchar="0",strict=TRUE)
x |
Input argument (converted to character) |
len |
Desired length of output |
padchar |
Character to pad x with, defaulting to “0”. |
strict |
Boolean variable governing the behaviour when length of
x is less than len . Under these circumstances, if
strict takes the default value of TRUE , then
return an error; if FALSE , return a truncated version of x
(least significant characters retained). |
