Replace <NA> with something else
I am reading some data into R from an Excel spreadsheet using read.csv. Some
of the original data that comes into column 1 from the spreadsheet is text
that says NA. The NA stands for north america. As it comes in, R converts
the NA over to <NA>.
What is the cleanest way to change the <NA> values to something else. In
other words, get rid of the brackets ? Maybe convert <NA>
