I think if you attach the output file would make clear. I guess it
is very likely your merge has the problem, not the write.table.
No. The merge woks fine. write.table is not writing the date indices
but write.zoo would. Tested.

You may need "by" parameter in merge based on the date. It also
could be date value is converged to numeric value, in this case you
just need to convert it back.

Hi,
I have attached the data files to this note. I use this code:
library(zoo)
z1 <- read.zoo("baltimorefludata.txt", format = "%m/%d/%Y", header =
TRUE)
z2 <- read.zoo("baltimorew.txt", format = "%Y%m%d", header = TRUE)
z3<-merge(z1,z2)
write.table(z3, "fluweatherdata_baltimore2.txt", sep="\t")
R is writing the other data to the file but not the dates... Is
there a way to also write the dates to the file? Thank you!!
Sincerely,
tom
