i want to select June, July and August data from the 3D array (`ssta_sst`,
360*180*362).
the loop works but the output of ssta_winter has the identical values for
`ssta_winter[,,i]`.seen below. I have set it up as an array of (360,180,29).
I think the problem is the variable `temp`, i want to define it as an array
first but i don't know what size it should be (360,180,3) or (360,180,3*29)
and how to keep a loop counter in `temp` when it passes down to finding mean
stage?
ssta_winter = array( data=NA, dim = c(360,180,29))
temp = array( data=NA, dim = c(360,180,3))
for (yr in 1982:2010) {
temp <- ssta_sst[,,year_sst==yr & (month_sst>=6 & month_sst<=8)]
for (i in 1:360) {
for (j in 1:180) {
ssta_winter[i,j,] <- mean(temp[i,j,])
}
}
}
> for (i in 1:29){
+ print(ssta_winter[180,166,i])
+ }
