datw$CO2k=1000*(datw$CO2)
Error in 1000 * (datw$CO2) : non-numeric argument to binary operator

It seems that datw$CO2 is not numeric. You can check this with

class(datw$CO2)

If it is indeed not numeric, please post the output of

dput(head(datw$CO2))

so we can see what type of data is in the CO2 column.
