Well, you have no reproducible example, but I suspect either of these will fix it: locals <- z[z$country == mycountry & !is.na(z$country),] locals <- subset(z, country == mycountry) Sarah On Wed, Sep 19, 2012 at 1:50 PM, Sam Steingold <sds at gnu.org> wrote:> I see this: > --8<---------------cut here---------------start------------->8--- >> length(which(is.na(z$language))) > [1] 0 >> locals <- z[z$country == mycountry,] >> length(which(is.na(locals$language))) > [1] 229 > --8<---------------cut here---------------end--------------->8--- > where are those locals without the language coming from?! >-- Sarah Goslee http://www.functionaldiversity.org
At least provide a reproducible example by creating the problem with a subset of 'z' and 'mycountry' Could something like this be happening?> x <- data.frame(country = 1:5, language = 1:5) > mycountry <- NA > z <- x[x$country == mycountry,] > zcountry language NA NA NA NA.1 NA NA NA.2 NA NA NA.3 NA NA NA.4 NA NA On Wed, Sep 19, 2012 at 1:50 PM, Sam Steingold <sds at gnu.org> wrote:> I see this: > --8<---------------cut here---------------start------------->8--- >> length(which(is.na(z$language))) > [1] 0 >> locals <- z[z$country == mycountry,] >> length(which(is.na(locals$language))) > [1] 229 > --8<---------------cut here---------------end--------------->8--- > where are those locals without the language coming from?! > > -- > Sam Steingold (http://sds.podval.org/) on Ubuntu 12.04 (precise) X 11.0.11103000 > http://www.childpsy.net/ http://ffii.org http://honestreporting.com > http://camera.org http://www.memritv.org http://dhimmi.com > I don't like cats! -- Come on, you just don't know how to cook them! > > ______________________________________________ > R-help at 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.-- Jim Holtman Data Munger Guru What is the problem that you are trying to solve?

I don't.
You are getting to be a regular around here, so you should know better by now.
Please stop posting non-reproducible sample code.
