Calculate the Average Number of Active Needles for Each Row in a Data Frame

This function takes a data frame that contains columns starting with "fraction" and containing "active_needles". It calculates the average number of active needles for each row, rounds it, and adds this as a new column to the data frame. If the average is NaN, it is replaced with NA.

Usage

add_average_active_needles(df)

Arguments

df

A data frame containing columns that start with "fraction" and contain "active_needles". These columns should contain numerical values.

Value

A data frame with an additional column `average_nr_active_needles` that contains the rounded average number of active needles for each row. If the average was NaN, it is replaced with NA.

Examples

if (FALSE) { # \dontrun{
df <- data.frame(fraction_1_active_needles = c(1, 2, 3),
                 fraction_2_active_needles = c(3, 4, 5),
                 some_other_column = c('a', 'b', 'c'))
average_active_needles(df)
} # }
