In timriffe/DDSQLtools: Wrappers for DemoTools Functions to Work with UNPD SQL Internal Data Format

Description

A generic checking utility. This will need various presets of values for the various possible columns, and may have its own wrappers for each.

Usage

check_values(x, expected.values, categorical = FALSE)

Arguments

x	vector of values, factor,character,numeric,integer, etc.
expected.values	set of valid values if categorical == TRUE, otherwise the valid value range.
categorical	logical. Does the value represent categories? Default FALSE for magnitudes or similar.

Details

make sure values in a column are as expected

Examples

expected.values <- c(0,1)
# can be a check on probabilities, perhaps they're in logit and we dont' realize it?
x <- runif(10)
x <- log(x/(1-x))
#out <- try(check_values(x,c(0,1),categorical = FALSE))
# de facto unit test..
#stopifnot(class(out) == "try-error")

# factors are checked against characters here.
y <- as.factor(c("a","b","c"))
check_values(y,letters,categorical = TRUE)
