Re: [R] How to plot wind direction and strength field

Hi Jim, I forgot to say that I don't want to create curved arrows, just straight - and I would like them to be proportional to the magnitude :o) Thanks again for your time! Jenny On Tue, 29 Apr 2008, Jenny Barnes wrote: Hi Jim, I would like to plot something like figure 2 on this webpage:

Thanks Jim - here is some data: u <- array(NA,c(5,8)) t <- seq(from=0.5, to=0.11,length=15) t2 <- seq(from=(-0.7),to=(-0.1),length=25) u[1:15] <- t u[16:40] <- t2 v <- array(NA,c(5,8)) y <- seq(from=(-0.9), to=(-0.01),length=40) v[1:40] <- y I've made up the data but it's similar magnitude and t

Re: [R] How to plot wind direction and strength field

Hi Jim, I would like to plot something like figure 2 on this webpage: http://www.cnrfc.noaa.gov/storm_summaries/jan1997storms.php My data is very large - covering the whole globe at 2.5deg resolution so longitude=144 girds, latitude=73 grids and time=32 years - hard to give you that data..
