Hi R-helpers,
I am trying the following code in R
merge(x=Master1,y=demo_dtls,by.x=c("ID_CASE","ts"),by.y=c("ID_CASE","TS_EVENT"))
where,
class(demo_dtls$TS_EVENT)
[1] "POSIXct" "POSIXt"
class(Master1$ts)
[1] "POSIXct" "POSIXt"
and
> class(Master1)[1] "data.table" "data.frame"> class(demo_dtls)[1] "data.frame"
But I am getting the following error
Error in merge.data.table(x = Master1, y = demo_dtls, by.x = c("ID_CASE", :
Can not match keys in x and y to automatically determine appropriate
`by` parameter. Please set `by` value explicitly.
Why am I getting this error?
Any help will be appreciated
