Hi there,
From the vector X of integers,
X = c(11999, 122000, 81997)
I would like to make these two vectors:
Z= c(1999, 2000, 1997)
Y =c(1 , 12 , 8)
That is, each entry of vector Z receives the four last digits of each entry of
X, and Y receives the rest.
Any suggestions?
Thanks in
Hi Dimitri,
You could write
z - trunc(x/1)
z
[1] 1 12 8
y - x-trunc(x/1)*1
y
[1] 1999 2000 1997
And there you have it.
Cheers,
Anne Hertel

Er, we do have integer divide and remainder operators:
X = c(11999, 122000, 81997)
X %% 1e4
[1] 1999
