Can anyone help me how to open little endian and big endian binary files in r. or any code in r to covert binary files in to geotiff.

library(ggplot2)
library(viridis)
library(viridisLite)
library(digest)
library(raster)
file("D:/dddd/binary/CMORPH+MWCOMB_DAILY-025DEG_20170301", "rb")
ls(zz)
ls()
column.names=readBin(zz, character(), n=10)
column.names
varnames = readBin(zz, character(), n=4)
varnames
datavals = readBin(zz, integer(), size = 4, n = 600, endian = "little")
readvals = datavals[1:200]
writevals = datavals[201:400]
mathvals = datavals[401:600]
rdata = cbind(readvals, writevals, mathvals)
colnames(rdata) = varnames

    There are lots of different types of binary file. Do you have any information about the format - like which program produced it, or how the data is supposed to be arranged within it? – Allan Cameron Mar 08 '20 at 09:07
