Re: [R] gridding values in a data frame

Thank you for your input. I will give it a try and see how it works out. I always have the same problem when programming...I always make things more complicated than they really are :-). Much appreciated. jdeisenberg wrote: > > > > dxc13 wrote: >> >> Hi all, >> I have a data frame that look

Re: [R] gridding values in a data frame

It's hard to check without a reproducible example, but the following code should give you a 3d array of lat x long x time: library(reshape) df$lat <- round_any(df$LATITUDE, 5) df$long <- round_any(df$LONGITUDE, 5) df$value <- df$TIME cast(df, lat ~ long ~ time, mean) On Thu, Apr 30, 2009 at 10

[R] gridding values in a data frame

Hi all, I have a data frame that looks like such: LATITUDE LONGITUDE TEMPERATURE TIME 36.73 -176.4358.32 1 50.9590.0074.39 1 -30.425.4523.26 1 15.81 -109.3152.44 1
