Dear All,

I am trying to replace a value of 528.8933 to -9999 in my file

t<- file("C:\\Users\\Amin\\Desktop\\1999n_Resample11.img", "rb")
e=readBin(t, double(), size=4,n=720*360, signed=TRUE)
e[e != -9999] <- e[e != -9999]*0.0099 + 477.65 -273.15                    
##worked well and values heve been calculated
e[e == 528.8933] <- -9999                            ## no changes made to
528.8933

any suggestions please
