Using R package BerkeleyEarth

I'm working for the first time with the R package BerkeleyEarth, and attempting to use its convenience functions to access the BEST data. I think maybe it's just a problem with their servers (a matter I've separately addressed to the package's maintainer) but I wanted to know if it's instead something silly I'm doing.

To reproduce my fault

library(BerkeleyEarth)
downloadBerkeley()

which provides the following error message

trying URL 'http://download.berkeleyearth.org/downloads/TAVG/LATEST%20-%20Non-seasonal%20_%20Quality%20Controlled.zip'
Error in download.file(urls$Url[thisUrl], destfile = file.path(destDir,  : 
  cannot open URL 'http://download.berkeleyearth.org/downloads/TAVG/LATEST%20-%20Non-seasonal%20_%20Quality%20Controlled.zip'
In addition: Warning message:
In download.file(urls$Url[thisUrl], destfile = file.path(destDir,  :
  InternetOpenUrl failed: 'A connection with the server could not be established'

Has anyone had a better experience using this package?

The error message is pointing to a different URL than one should get judging what URLs are listed at http://berkeleyearth.org/data/ that point to the zip formatted files. There are another set of .nc files that appear to be more recent. I would replace the entries in the BerkeleyUrls dataframe with the ones that match your analysis strategy:

This is the current URL that should be in position 1,1:

http://berkeleyearth.lbl.gov/downloads/TAVG/LATEST%20-%20Non-seasonal%20_%20Quality%20Controlled.zip

And this is the one that is in the package dataframe:

> BerkeleyUrls[1,1]
[1] "http://download.berkeleyearth.org/downloads/TAVG/LATEST%20-%20Non-seasonal%20_%20Quality%20Controlled.zip"

I suppose you could try:

 BerkeleyUrls[, 1] <- sub( "download\\.berkeleyearth\\.org", "berkeleyearth.lbl.gov", BerkeleyUrls[, 1])
