r - remove a character from the entire data frame -


i have dataframe various columns, of data within columns contain double quotes, want remove these, eg:

id    name   value1     value2 "1     x     a,"b,"c     x" "2     y     d,"r"       z"

i want this:

id    name   value1    value2 1     x      a,b,c      x 2     y      d,r        z

i use lapply loop on columns , replace " using gsub.

df1[] <- lapply(df1, gsub, pattern='"', replacement='') df1 #  id name value1 value2 #1  1    x  a,b,c      x #2  2    y    d,r      z

and if need class can changed type.convert

df1[] <- lapply(df1, type.convert)

data

df1 <-  structure(list(id = c("\"1", "\"2"), name = c("x", "y"), value1 = c("a,\"b,\"c",  "d,\"r\""), value2 = c("x\"", "z\"")), .names = c("id", "name",  "value1", "value2"), class = "data.frame", row.names = c(na, -2l))

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
