Hello,
I have a zoo time series object (say a) with the following time
stamp/format
[1] "1950-01-03 GMT" "1950-01-04 GMT" "1950-01-05 GMT" "1950-01-06 GMT"
[5] "1950-01-09 GMT" "1950-01-10 GMT"
and another (say b) with
[1] "1950-01-05" "1950-01-06" "1950-01-09" "1950-01-10" "1950-01-11"
[6] "1950-01-12"
I want to merge these series but when I try:
> head(merge(a, b ))
a b
1950-01-03 02:00:00 16.66 NA
1950-01-04 02:00:00 16.85 NA
1950-01-05 02:00:00 16.93 NA
1950-01-06 02:00:00 16.98 NA
1950-01-09 02:00:00 17.08 NA
1950-01-10 02:00:00 17.03 NA
Warning message:
In merge.zoo(a, b) :
Index vectors are of different classes: POSIXt Date
>
Anybody can help? I tried as.POSIXct(a,tz="GMT") but it doesn't seem to
work....
Many thanks in advance!
