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
+ )> closeAllConnections()
