Hello,
I'm doing the following:
library(ncdf)
library(fields)
library(animation)
saline <- open.ncdf("salinity_1990.nc")
salt = get.var.ncdf(nc=saline, varid="Salinity")
# create an animation of the complete temporal domain in the ncdf file.
saveHTML({
for (i in 1:364) {
image.plot(salt[, , i])
}
}, img.name = "salinity.img", imgdir = "salinity_dir", htmlfile =
"salinity.html", zmax = c(0, 80),
autobrowse = FALSE, title = "TIME SALINITY PREDICTIONS",
description = c("This should plot 1 years daily salinity
predictions in Florida Bay")
)
Almost all of the data sets I work with are multi-temporal spatial forms.
Being able to view the time sequence is very important to us, The animation
procedure is very good. I appreciate its development.
Here are my questions.
1) I would like to find a procedure to set the maximum value of the legend
of an image.plot. Each time step has a different maximum value, but for
the animation to be valuable, I need to standardize these to a maximum such
that the scale is equal in each time step.
2) Secondly, when setting imgdir it only goes to a temp directory. If I
define a directory, the new directory path is added to the default temp
directory path. Is there a way to fix this so that the output directory is
truly defined in the saveHTML statements?
I'm working on a windows XP machine using R 2.12.1.
Thanks
Steve
