Opening SAS file using read.sas7bdat() function in sas7bdat library.

Dear all,

Thank you for the response and.. thanks Marc.
It works with the source file which Matt has at
https://github.com/BioStatMatt/sas7bdat/blob/master/R/sas7bdat.R
which is also attached.

Cheers,

Praveen.

Hi,



I have a file in .sas7bdat format. I tried to open this file using
read.sas7bdat() function.

This gave me an error - "Error in read.sas7bdat("bnp_genetic.sas7bdat")

:

 unknown host X64_7PRO".

Could someone tell me what this error means?

Thank you,

Praveen.

More than likely, a similar problem as in this recent thread, but for 64

bit, rather than 32 bit:

  https://stat.ethz.ch/pipermail/r-help/2012-October/325257.html

If you look at the source for the function, it checks the "SAS_host"

against a known list, containing

# Host systems known to work
KNOWNHOST <- c("WIN_PRO", "WIN_NT", "WIN_NTSV", "WIN_SRV",
              "WIN_ASRV", "XP_PRO", "XP_HOME", "NET_ASRV",
              "NET_DSRV", "NET_SRV", "WIN_98", "W32_VSPR",
              "WIN", "WIN_95", "X64_VSPR", "X64_ESRV")

Praveen's host is not in that list, so the package author has never tested

it.   But nothing else in the code appears to depend on the host, so it's a
good guess that adding another host string to that list (or changing the
error to a warning) will make it work properly.

As per that prior thread, Matt has added those to the source on GitHub:

  https://github.com/BioStatMatt/sas7bdat/blob/master/R/sas7bdat.R

at line 86:

# Host systems known to work
KNOWNHOST <- c("WIN_PRO", "WIN_NT", "WIN_NTSV", "WIN_SRV",
               "WIN_ASRV", "XP_PRO", "XP_HOME", "NET_ASRV",
               "NET_DSRV", "NET_SRV", "WIN_98", "W32_VSPR",
               "WIN", "WIN_95", "X64_VSPR", "X64_ESRV",
               "W32_ESRV", "W32_7PRO", "W32_VSHO", "X64_7HOM",
               "X64_7PRO", "X64_SRV0")


It's presumably just a matter of Matt releasing an updated version of the
package. There were some comments in that prior thread of communication
issues with Matt, so not sure what is going on there relative to time frame.

Marc
