Dear All
I have a character vector, representing histology stages, such as for example:
xc <- c("1", "1a", "1b", "1c", "2", "2a", "2b", "2c")
and this goes on to 3, 3a etc in various order for each patient. I do have of
course a pre-established classification available which does change according
to the histology criteria under assessment.
I would want to convert xc, for plotting reasons, to a numeric vector such as
xn <- c(1, 1.3, 1.5, 1.7, 2, 2.3, 2.5, 2.7)
Unfortunately I have no clue on how to do that.
Thanks for any help and apologies if I am missing the obvious way to do it.
JL
