I think you want to make sure you read it is as character:
> x <- read.table(textConnection('"swissProtID" "entrezID" "bitVec"
+ "Q62924" "---" "00000000100010000000000000000000"
+ "P18897" "---" "00000000000001000100000000000000"
+ "Q62736" "---" "00001000001000000000001000000000"
+ "P13589" "---" "00100000010000010000000000000000"')
+ , colClasses = rep('character', 3)
+ , as.is = TRUE
+ , header = TRUE
+ )
