Unite multiple columns in an ir object into one by pasting strings together

Unite multiple columns in an ir object into one by pasting strings together

Usage

unite.ir(data, col, ..., sep = "_", remove = TRUE, na.rm = FALSE)

Source

tidyr::unite()

Arguments

data

An object of class ir.

col

The name of the new column, as a string or symbol.

This argument is passed by expression and supports quasiquotation (you can unquote strings and symbols). The name is captured from the expression with rlang::ensym() (note that this kind of interface where symbols do not represent actual objects is now discouraged in the tidyverse; we support it here for backward compatibility).

...

<tidy-select> Columns to unite

sep

Separator to use between values.

remove

If TRUE, remove input columns from output data frame.

na.rm

If TRUE, missing values will be removed prior to uniting each value.

Value

.data with united columns. If the spectra column is dropped or invalidated (see ir_new_ir()), the ir class is dropped, else the object is of class ir.
