Works for me. Can you make a reproducible example [1] the way the
footers of all emails on this list ask you to? The str and dput functions
are very useful tools mentioned in the referenced article.

Hi Peter,
Thanks for your reply, I tried to convert my data.table into a data.frame
and then merging but I am getting the same error. But when I check the
class of my previously data.table object it returns "data.frame".
Any clue as to why this is happening?
Regards

Because merge.data.table expects both objects to be data.table objects?

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_dtl
