[R] R does not recognise columns and rows as they are supposed to be

[Jonsson]

I tried to read only one file and get some information but this is what I
got:

sam=file("C:\\Users\\2001\\SWdown_200101_01.img", "rb")
 file1<- readBin(sam, double(),size=4,  n=360*720) 
 file.info(file1)$size
Error in file.info(file1) : invalid filename argument
dim(file1)
NULL
