 data.frame: newdf

 var1 var2 var3 var4
 A   1  0 4
 B   3  2 1
 C   0  5 1

 My real data frame has several more variables.

 I am using the recode function from the epicalc package:

   recode(vars=newdf[, 2:4], old.value= newdf[, 2:4] >= 1, new.value=1)

 I guess I am not setting the condition in a proper way.

 Best,

 Manuel

Not very elegant or efficient, but for only a couple of columns needing 
left out something simple like this should work.


xx=data.frame(x=c(2, 10), y=c(2, 0), z=c(4, 3))
yy=xx[,2:3]
yy[yy!=0]=1
data.frame(x=xx[,1], yy)
