read_tdf(x, ...)

## S3 method for class 'character'
read_tdf(
  x,
  missing = -1,
  weight = FALSE,
  ncovars = 0,
  labels = character(0),
  ...
)

## S3 method for class 'trimcommand'
read_tdf(x, ...)

Arguments

• x: a filename or a trimcommand object
• ...: (unused)
• missing: [integer] missing value indicator. Missing values are translated to NA.

Variable	status	R type
site	requiered	integer
time	required	integer
count	required	numeric
weight	optional	numeric
<covariate1>	optional	integer
...
