column_sums {fritools2}

Sum up the Numeric Columns of a Data Frame

Description

I often need to calculate the sums of the numeric columns of a data.frame. While colSums requires the data frame to be numeric, this is a convenience wrapper to select numeric columns only.

Usage

column_sums(x, ...)

Arguments

x

A data.frame.

...

Arguments passed to colSums.

Value

A named vector of column sums (see colSums).

Examples

try(colSums(iris))
column_sums(iris)
names(iris) # no column sum for `Species`
