Re: [R] Converting IEEE Float in 16 char hex back to float

Hi, DSREAD utility solves the 200 byte, 8 char name and potential precision errors with other methods of transfering SAS datasets to perl and R. Importing SAS datasets(sas7bdat) into R (32 bit windows 2000, 32 bit SAS 9.2 and 32 bit R version 2.9.0 (2009-04-17) Here is what I want to

Re: [R] Converting IEEE Float in 16 char hex back to float

Thanks Nice code. I appreciate the function. I don't know if you ever use SAS datasets but I am working with the devloper of 'dsread' to create a lossless transfer from SAS to R. I am also working on an in memory Java interface which would allow me to mix SAS and R code. Here is the link to dsr
