I am trying to read a fixed width file from U.S. Census Bureau into R using read_fwf(). I keep getting an error in the same place in the list of column names. I have tried to change the particular column name at the location in multiple attempts and R keeps throwing the error. I restarted R to a new session and I keep getting the error. In the list of column names, it's the 39th item that seems to have the problem. I've changed the name of the 39th, and sometimes the 38th, position in one of the attempts I've included in code. The first line of code in the code block has the original column name values. In that line, the 39th name is "cbsac", but the error prints that as "... "" ". It's close to the name in the 38th position, "cbsa", but a lot of the names in succession in other parts of the list are very similar and they don't cause an error. I don't know what that is supposed to indicate. Does "cbsac" mean something in R that I'm not aware of?
