Hi,
I am new to R and am using quilt.plot (from fields package) to plot gas
concentrations in Europe.
I am using the following code to plot my data
library(maps)
library(fields)
test = read.csv("%change 1996_2005.txt", sep="\t")
colnames(test) = c("Station", "Measurement_BaseO3",
"Model_BaseO3", "Measuerment_PeakO3",
"Model_PeakO3", "Longitude", "Latitude")
quilt.plot(test$Longitude, test$Latitude, test$Model_BaseO3,
breaks = c(-50, -40, -30, -20, -10, 0, 10, 20, 30, 40, 50), col =
tim.colors(10),
xlim=c(-11,25), ylim=c(40,60), zlim=c(-50, 50), xlab="Longitude",
ylab="Latitude", asp=1,
main="Modelled Base Ozone")
map(add=TRUE)
It all plots beautifully, except the size of the plotted data points is far too
small. I have tried using "cex = xx" into quilt.plot() to change the
size of the data points but that doesn't seem to work. Maybe I am just using
this wrong?!
I was wondering if someone could help me to alter the data point size (increase
it to x 3 the current size).
Thanks,
Becca
