title: Is there an R function to convert non-standard scientific notation?
body: <p>I'm presently working with a dataset (made from a biostatistics research project) which denotes expression ranks in a value such as "1.00e3" rather than "1.00e+03" which seems to confuse the system when ranking. Does anyone have any ideas as to how to work within the data frame to force it to convert "e" notations to standard form? I have already tried scipen and formatC. </p>
