Turns a factor into a number
Turning a factor into a number is not trivial.
Using as.numeric
would only return to us the indicator numbers
and NOT the factor levels turned into a number.
fac2num simply turns a factor into a number, as we often need.
fac2num(x, force_integer = FALSE, keep_names = TRUE, ...)
x |
an object. |
force_integer |
logical (FALSE). Should the values returned be integers? |
keep_names |
logical (TRUE). Should the values returned keep the names of the original vector? |
... |
ignored. |
if x is an object - it returns logical - is the object of class dendrogram.
x <- factor(3:5) as.numeric(x) # 1 2 3 fac2num(x) # 3 4 5
