This function creates dummy variables for each input column, setting 1 if the value is above zero, 0 if it's zero, and NA if it's below zero. It then sums these dummy variables to create a count.
Usage
count_if_above_zero(df, vars, new_colname)
Arguments
- df
A data frame containing the columns to be processed.
- vars
Vector of column names to be processed.
- new_colname
The name of the new column that will contain the count.
Value
A data frame with additional columns:
"*_d": Dummy variables for each input column, where 'star' is the original column name.
new_colname: A new column containing the count of values above zero across the specified variables.
