Hello everyone, I have the following problem, I have a dataframes that looks like this:
fire$Year fire$Size 1 1981 1738.0 2 1984 2228.1 3 1985 38963.3 4 1986 2223.4 5 1987 3594.6 6 1988 1520.0 ... What I would like to do is copy the values from the fire$Size colum and put it into a new df but with "0" for the years that are missing. The result should look like this: year size 1981 1738.0 1982 0 1983 0 1984 2228.1 ... First I tried to merge the two dataframes temp <-merge(fire.sum,fire2, by.x="fire$Year", by.y="year") but then it only gives me the years that are the same. So I thought it might be easier to just copy them? Any help is appreciated, thank you so much Cheers Sandra -- View this message in context: http://r.789695.n4.nabble.com/copy-values-from-one-dataframes-into-another-tp3321805p3321805.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
