Hi!
Thank you for great tool! There is mistake in ?blast documentation.
R needs to be able to find the executable (mostly an issue with Windows). Try Sys.which("blastn") to see if the program is properly installed. If not, then you probably need to set the environment variable called PATH using something like Sys.setenv(PATH = paste(Sys.getenv("PATH"), "path_to_BLAST", sep=":")).
