Convert other formats to binary flags.

1	binarize.vals(x, val0, val1, ignore.case = TRUE)

`x`	a vector.
`val0, val1`	the values to convert to 0/1 respectively.
`ignore.case`	if TRUE, conversion will ignore
`as.numeric`	if TRUE, return a numeric vector else return a string.

A new vector of zeroes and ones.

Flags/indicators are stored in different formats. This function converts two arbitrary values to 0/1. Others will be converted to NA. The default behavior ignores case, e.g. binarize.vals(x, 'Y', 'N') will convert 'Y' to 0 but 'y' to NA. Setting ignore.case = FALSE will first convert all

TRUE is not 'true'! Setting ignore.case = FALSE when converting T/F will not work as desired. The function should catch this by checking is.logical(x).

x <- c(sample(c('Y', 'N'), 5, replace = T), 'a', 'y', 0, 'n')
print(x)
binarize.vals(x, 'Y', 'N')

x <- c(T, F, T, T, F)
binarize.vals(x, 'T', 'F', ignore.case = F)  # wrong
