# S3 method for trimcommand
read_tdf(x, ...)
a filename or a trimcommand object
(unused)
[integer] missing value indicator.
Missing values are translated to NA.
[logical] indicate presence of a weight column
[logical] The number of covariates in the file
[character] (optional) specify labels for the covariates.
Defaults to cov<i> (i=1,2,...,ncovars) if none are specified.
A data.frame.
TRIM input data is stored in a ASCII encoded file where headerless columns
are separated by one or more spaces. Below are the columns as read_tdf expects
them.
| Variable | status | R type |
site |
requiered | integer |
