Hey guys, I have the same question, except in reverse: if we had letter
classifications and wanted to assign numerical values to them (the case I
stated previously except the other way around) how would we do that? I am
trying to use the recode function in the car package but not having any
willsclahanstationcut$wills.vs30-
recode(willsclahanstationcut$area.VSCAT,c(B=686,C= 464,BC= 724,
D=301,CD= 372, D= 800, DE= 1000, WATER=0))
where $vs30 is the column I want to create, $area.VSCAT is the column which
contains the labels.

hello all,
I have a data frame and I want to create a column which assigns a letter
based upon the value in another column. The data column has velocities
ranging from 0 to 1000. So for example, for velocities between 0 and 300
I'd like to assign the letter A in the new column, for 300-600, B
Dear Medhi,
Take a look at ?cut or ?recode (in the car package).
HTH,
Jorge

have a look at ?cut(); for instance,
x - sample(1000, 20, TRUE)
x
cut(x, c(0, 300, 600, 1000), c(A, B, C))
I hope it helps.
Best,
Dimitris

Try this:
cut(sample(0:1000, 100), breaks = c(0, 300, 600, 900, 1000), labels = c('A',
'B', 'C', 'D'))
