I just upgraded to 2.01 on Mac OS 10.3.6. I used to use the command
(on R 1.9.x):
world(ylim=c(-30,30), xlim = c(0,360), shift=TRUE, add=TRUE)
to draw a world outline over my image plots. My data uses longitude
from (0, 360) so I need to use the shift function. After I upgraded, I
get the following error:
world(ylim=c(-30,30), xlim = c(0,360), shift=TRUE, add=TRUE)
Error in world(ylim = c(-30, 30), xlim = c(0, 360), shift = TRUE, add =
TRUE) :
NAs are not allowed in subscripted assignments
Does anyone know a workaround for this?
Well, a workaround would be:
library(maps)
map(world2, ylim=c(-30,30), xlim = c(0,360), add = TRUE)
(at least until fields is updated).
CHANGES IN R VERSION 2.0.0
o Subassignments involving NAs and with a replacement value of
length 1 are now disallowed. (They were handled
inconsistently in R 2.0.0, see PR#7210.) For data frames
they are disallowed altogether, even for logical matrix indices
(the only case which used to work).
