Hellow everyone,
This code bellow will calculate average daily wind speed(measurements are
taken every three hours).Any ideas how to take the Min and Max instead of
average.
library(Matrix)
setwd("C:\\Users\\aalyaari\\Desktop\\img")
listfile<-dir()
long <- file("C:\\Users\\aalyaari\\Desktop\\New folder (5)\\inra.bin", "rb")
A=readBin(long, integer(), size=2,n=67420*1, signed=F)
ta<-t(A)
lot <- file("C:\\Users\\aalyaari\\Desktop\\New folder (5)\\lat.img", "rb")
B=readBin(lot, integer(), size=2,n=67420*1, signed=F)
tb<-t(B)
for (n in 1:length(listfile))
{
#h[n]=listfile[n]
h=listfile[n]
#b[n]=file.info(h[n])$size/67420/4
b=file.info(h[n])$size/67420/4
wind <- file(h, "rb")
C=readBin(wind, double(), size=4,n=67420*b, signed=TRUE)
D<-matrix(C,nrow=b,ncol=67420)
for(d in 1:b)
{
M <- Matrix(-9999, 360, 720)
tm<-t(M)
for(i in 1:67420)
{
tm[ta[i],tb[i]]= round(10 * ((D[(d-1)*8+1,i] +
D[(d-1)*8+2,i]
+D[(d-1)*8+3,i] +D[(d-1)*8+4,i] +D[(d-1)*8+5,i] +D[(d-1)*8+6,i]
+D[(d-1)*8+7,i] +D[(d-1)*8+8,i] ) / 8))
}
to.write <- sprintf("C:\\Users\\aalyaari\\Desktop\\New folder
(6)\\Yar_%00d.bin", d)
writeBin(as.integer(tm@x), size=2,to.write)
}
}
