title: R read.delim error "no lines available in input"
body: <p>I'm having trouble downloading a particular tab delimited dataset from the USGS.gov in base R using <code>read.delim</code> or <code>read.table</code>. I'm probably making an obvious mistake, but I can't seem to figure out what. </p>
  
  <p>First, the following query functions fine in base R, and retrieves all water level data for the Markland Dam on the Ohio River. It also works for other dams. </p>
  
  <pre><code>Markland &lt;- read.delim(("https://nwis.waterdata.usgs.gov/ky/nwis/uv?cb_00065=on&amp;format=rdb&amp;site_no=03277200&amp;period=&amp;begin_date=1950-09-30&amp;end_date=2030-12-31"), 
                         stringsAsFactors=FALSE, skip=28, header=TRUE)
  </code></pre>
  
  <p>However, my query for another table, the McAlpine Dam downstream, does not work. The data are structured almost identically. I've toyed with all of the read options provided in the read.table help, to no avail. I'm not sure what's different about this table, or what needs to change with this query. </p>
  
  <pre><code>McAlpine &lt;- read.delim(("https://nwis.waterdata.usgs.gov/ky/nwis/uv?cb_00065=on&amp;format=rdb&amp;site_no=03294500&amp;period=&amp;begin_date=1950-09-30&amp;end_date=2030-12-31"), 
              skipNul=TRUE, blank.lines.skip=TRUE, sep = "\t", 
              stringsAsFactors=FALSE, skip=40, header=FALSE , fill=TRUE)
  </code></pre>
  
  <p>Here is the offending table: <a href="https://nwis.waterdata.usgs.gov/ky/nwis/uv?cb_00065=on&amp;format=rdb&amp;site_no=03294500&amp;period=&amp;begin_date=1950-09-30&amp;end_date=2030-12-31" rel="nofollow noreferrer">https://nwis.waterdata.usgs.gov/ky/nwis/uv?cb_00065=on&amp;format=rdb&amp;site_no=03294500&amp;period=&amp;begin_date=1950-09-30&amp;end_date=2030-12-31</a></p>
