Description Usage Arguments Value Examples

v_str is a vector of original string categories. cat_spec is a cateogry specification (see [parse_cat_spec]). Apply the category specification to each element of v_str to yield a new vector v_int, which gives the integer category values.

1	apply_cat_spec(v_str, cat_spec)

`v_str`	The vector of original string categories
`cat_spec`	The category specification

The vector of new, integer categories

# Call apply_cat_spec to assign category specification to trait string
v_str <- c("a",NA,"d","b","c",NA,"d","a")  # vector of string categories
cat_spec <- "a c d b"  # order of categories

# Expected application: a=0, c=1, d=2, b=3
# Therefore, expected output: c(0,NA,2,3,1,NA,2,0)
v_int <- apply_cat_spec(v_str, cat_spec)
print(v_int)
