lead.zeroes | R Documentation |
Returns the vector that was supplied, but with leading zeroes added where needed to make all elements have specified number of characters.
lead.zeroes(fips, length.desired)
fips |
Character vector, which can be FIPS codes or other data. Required. |
length.desired |
A single numeric value (recycled), or vector of numbers, required, specifying how many characters long each returned string should be. |
This function can be useful in working with Census data where FIPS codes are often used.
Moving data to and from a spreadsheet can remove leading zeroes that may be necessary for proper data management.
This can apply to e.g., FIPS code for a block, block group, tract, county, or state.
Note: Number of digits in FIPS codes, assuming leading zeroes are there:
state 2 (2 cumulative)
county 3 (5 cum)
tract 6 (11 cum) (note 11 digits is ambiguous if not sure leading zero is there)
block group 1 (12 cum) (note 12 digits is ambiguous if not sure leading zero is there)
block 1 (13 cum)
Returns a vector of same length as input parameter
lead.zeroes(c('234','01234','3'), 5)
