Unwanted paragraph breaks in TSV file

I am using Rstudio and trying to load in a txt document like so:

table <- read.table("association_test.assoc.txt",
                      as.is = "rs",header = TRUE)

However, I get this error:
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :
line 1 did not have 9 elements

Looking at the file, there is an unwanted line break, so my data looks like this:

  1. Header; [1] [2] [3] etc...
  2. Data; [a] [b]
  3. [c]
  4. [a2] [b2]
  5. [c2]

How do I delete these unwanted line breaks, so that [a, b, c] are all on the same row, rather than on different ones?

Thank you!

This needs a reprex. See the FAQ. Just cut and paste the first ten lines of the *.txt file will do for this one.

Can you share with us the tsv using dropbox for example?
