[R] FW: recoding problem

[Joshua Wiley]

Hi Tom,

This seems to work like I'd expect:

HGlt10RawPerc2008 <- read.table(textConnection("
-5
 0
-1
-1
 0
 2
 3
-5
-2
 0
 2
 0
 1
-2
 3
 0
 4
 1
 4
 2
"))

recode(HGlt10RawPerc2008 ,"-100:0.0 = 10; 0:1.0 = 8; 1.001:3.0 = 6;
3.001:4.0 = 4; 4.001:5.0 = 2; else = 0")

I wonder if your data might not be something like 10.0000001 which
would print as 10, but behave in calculations slightly differently?

Also, the output of this might be informative.

str(HGlt10RawPerc2008)

Cheers,

Josh
