seek(), skip by bits (not by bytes) in binary file
...39;junk' bits from the to.read file which is huge integer so
I divide it up and loop through to.read in parts (jb_part).
divr = 20
mod = junk %% divr
jb_part = as.integer(junk/divr)
jb_part_mod = jb_part + mod # catch the remainder/modulus
to.read = file(paste(dbs_path,"/",dbs_file,sep=""),"rb") # connect to the
binary file
# loop in chunks to where I want to be
for(i in 1:(divr-1)){
x = readBin(to.read,"raw",n=jb_part,size=1)
x = NULL # trash the result b/c I don't want it
}
# read a a little more to include the remainder/modulus...
