Hi All I am trying to find a way to prevent column names from changing on zoo objects when I merge them. I have column names that contain a "-" that after merging have become "." # Example zz1 = zoo(as.matrix(1:5)) zz2 = zoo(as.matrix(10:12)) names(zz1)=c("aa-1") names(zz2)=c("bb-1") zz3=merge(zz1,zz2)
merge(zz1, zz2, check.names = FALSE) should do what you want. (This is also the default in the devel version on R-Forge.) hth, Z
print(zz3) Obviously, I could do something like names(zz3) = c(names(zz1),names(zz2)) but I have a large number of zoo objects that I am merging. Creating the simple line above is not that easy. Any thoughts would be gratefully received.
