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()

> x
swissProtID entrezID bitVec

> str(x)
'data.frame': 4 obs. of 3 variables:
$ swissProtID: chr "Q62924" "P18897" "Q62736" "P13589"
$ entrezID : chr "---" "---" "---" "---"
$ bitVec : chr "00000000100010000000000000000000"
"00000000000001000100000000000000" "00001000001000000000001000000000"
