filter and merge 2 big Df's by=t_chr in sec.
...2*c(1:length(t_chr2)),dfb.c=0.1*c(length(t_chr2):1))); Df.b
#------------------------------------------
merge(Df.a,Df.b, by.x=t_chr,by.y=t_chr2,all.x=TRUE,all.y=TRUE)
And if in Df.a there is no all seconds measurements?
And if in Df.a. there are many NA?
How we can handle it in R?
Thanks
KaluzaEA.
