[R] Strange Colnames

[Georg Hoermann]

Hello world,

I am trying to create a matrix of lagged time series with the
following code fragment (I know that I can use acf-function...).
I want to set the variable/column name to something like
"lag 1" etc. If I try to do it I get text like
"lagtest.lagtest.lagtest.lag 1" where does this come from?

After a conversion to a data.frame it works as expected.
What did I miss?

Thanks and greetings,

Georg

 > lagtest <- as.ts(seq(1:100)) ;
 > for (i in 1:4) {lagtest <- cbind(lagtest,lag(ts_test,i)); 
colnames(lagtest)[i+1]<- paste("lag",i)}
 > colnames(lagtest)[1]<-"H_GW";
 > colnames(lagtest)
[1] "H_GW"                          "lagtest.lagtest.lagtest.lag 1" 
"lagtest.lagtest.lag 2"
[4] "lagtest.lag 3"                 "lag 4"


# this works...

 >  t5 <- as.data.frame(lagtest)
 > for (i in 1:4) {names(t5)[i+1] <- paste("var",i) }
 > names(t5)
[1] "H_GW"  "var 1" "var 2" "var 3" "var 4"
