Compute the number or count of matching conditions

Computes the number of conditions (provided as a character vectorcond), involving the input variables vars, that were found to be TRUE. Options available to exclude certain values from the input variables (provided as a character vector exclude).

Usage

ss_count_cond(data, name, vars, exclude = NULL, combine = FALSE, cond, max_na)

Arguments

data

tbl. Data frame containing the columns to be summarized.

name

character. The name of the summary score.

vars

character vector. The names of the columns to be summarized.

exclude

character (vector). The value(s) to be excluded (Default: NULL; all values are used).

combine

logical. Whether to combine the summary score column with the input data frame (Default: FALSE).

cond

character vector. Each specified condition, involving the values of specific input fields, gets tested for 1 (TRUE) or 0 (FALSE). If a condition is specified as "field_name", the numeric value in the field is counted and could be greater than 1. Whereas other conditions when met can get a value of 1 or 0. The summary score is a sum over all the values obtained from testing each condition specified in cond.

max_na

numeric, positive whole number. Number of missing items allowed.

Value

tbl. The input data frame with the summary score appended as a new column.
