remove_rows_n

Removes rows that contain 'NA' and/or 'Inf' entries

Description

This function removes any rows in which an 'NA' or an 'Inf' entry is found. The function is also able to remove records with 'Inf' entries, distinguishing it from the popular 'na.omit()' function in R.

Usage

remove_rows_n(traj, id_field=TRUE, remove=1)

Arguments

`traj`	[data.frame (numeric)]: longitudinal data. Each row represents an individual trajectory (of observations). The columns show the observations at consecutive time points.
`id_field`	[numeric or character] Whether the first column of the `traj` is a unique (`id`) field. Default: `FALSE`. If `TRUE` the function recognises the second column as the first time step.
`remove`	[integer] Type of missing entries to remove. `1` for 'NA', `2` for 'Inf', and `3` for both. Default:`1`.

Details

Given a matrix (or a dataframe) containing an 'NA' or an 'Inf' entry, the function returns only rows with complete observations.

Value

A matrix with complete observations
