hey boss, thanks for all your hard work. here's a reproducible example

# read_sas() fails on compressed .sas7bdat files
    # and gives an unhelpful error message
# read.sas7bdat() also fails, but explains why
# read.sas7bdat.parso succeeds

# load a few packages to demonstrate successes and failures
install_github( "biostatmatt/sas7bdat.parso" )

# initiate some temporary files
tfp <- tempfile() ; tff <- tempfile() ; tfh <- tempfile()

# three of the latest files from the us census bureau's current population survey
# the current population survey is the major federal benchmark for employment, poverty, and health insurance in the united states

download.file( "" , tfp , mode = 'wb' )
download.file( "" , tff , mode = 'wb' )
download.file( "" , tfh , mode = 'wb' )

# breaks
havenp <- read_sas( tfp )
# works
havenf <- read_sas( tff )
# breaks
havenh <- read_sas( tfh )

# breaks
sbdp <- read.sas7bdat( tfp )
# breaks
sbdf <- read.sas7bdat( tff )
# breaks
sbdh <- read.sas7bdat( tfh )

# works
parsop <- read.sas7bdat.parso( tfp )
# works
parsof <- read.sas7bdat.parso( tff )
# works
parsoh <- read.sas7bdat.parso( tfh )

quick note: read.sas7bdat.parso does not work either

Fixed in WizardMac/ReadStat@69d5751 and WizardMac/ReadStat@8c0463a

@hadley if you update to the latest ReadStat code you should be able to close this issue.

HI there, In trying to read_sas files, I am getting the "A row in the file was not the expected length." (it happens for all my SAS files) so after looking up, I follow the instructions here (and on the intro page) attempting to update to the latest ReadStat code. I now get the following:
Warning messages:
1: running command 'wget "" -O "C:\Users\Silvia\AppData\Local\Temp\Rtmpi0gQKP\file1f0823635f9b"' had status 127
2: In download.file("", :
download had nonzero exit status

Read the git use's manual, and I do see that the problem might be in wget. any suggestions on where to go from here?

I have spent a lot of time with these functions because I have a full library of SAS datasets that are too big to just dump into text files and read into R. Thanks for putting together the Haven library.
