Re: [R] how to use AND in grepl

Actually not sure my previous answer does what you wanted. Using your approach: t2pd=subset(df,grepl("t2",df$Command) & grepl("pd",df$Command)) Should work. I think the regex pattern you are looking for is: Subset(df,grepl("(.* t2.*pd.* )|(.* pd.* t2.*)",df$Command) On Sat, Apr 30, 2016,

Hi, I think you need to check the order of your arguments to rasterize(). See the documentation with ?rasterize and compare to what you did below. Cheers, Ben > On Apr 30, 2016, at 9:55 AM, Ogbos Okike wrote: > > Dear All, > Thanks for your inputs. I did replace

Hi Lars, A mystery, but for the bodgy characters in your error message. Perhaps there is a problem with R trying to read a different character set from that used in the package. Jim On Sat, Apr 30, 2016 at 8:22 PM, Lars Bishop wrote: > Hello, > > I can’t seem to be able to

There are several packages and functions that can do this (e.g. search on "3d surface plots" at rseek.org or internet search engine). You are much more likely to get a helpful answer if you provide a minimal data set (e.g. via dput() ) and code from any function(s) and package(s) that you tried.
