clip.column: Clip an integer column

In davidthaler/PUMSutils: Computes Point Estimates and Standard Errors on the ACS PUMS Data

Description

Many count variables in the ACS PUMS data have long upper tails. This function clips integer columns and returns a factor with level names like "1", "2", "3+" that order correctly, even if the clip level is named something like ">=3", which would not sort correctly as a string.

Usage

clip.column(x, colname, clip.at, clip.name = NULL)

Arguments

x	a data frame of PUMS data
colname	(string) name of column in x to clip
clip.at	upper clip level
clip.name	(string) name of the top clip level; for clip.at of n, the default is "n+".

Value

factor column with levels like "1", "2", ... "n+" in place of the (count) integer values in x$colname

Examples

wa.house16$Size <- clip.column(wa.house16, 'NP', 5, '>=5')
group.count(wa.house16, 'HH.Count', 'Size')
