...ortunately I can not find equivalent function in R. Simple minded:
doubleVec = (1:4)*pi
rawVec = as.raw(doubleVec)
as.double(rawVec)
Does not seem to work (output: 3 6 9 12, instead of: 3.141593 6.283185
9.424778 12.566371) .
The only way I figured out how to do it is by using:
raw2double = function(x)
{
writeBin(as.raw(x), "temp.bin")
return( readBin("temp.bin", "double", n=length(x)%/%8) )
}
double2raw = function(x)
{
writeBin(as.double(x), "temp.bin")
return( readBin("temp.bin", "raw", n=length(...
