r - Sudden "unused argument" error -


i have no idea why quite sure following did produce plot while back. can tell me what's wrong here?

library(ggplot2) qplot(c(0, 2), stat="function", fun=exp, geom="line")

this returns "error in c(0, 2) : unused argument (2)." why?

edit: general problem:

a <- c(0, 2)

gives same error. what's going on here?

works me ggplot2 v 0.9.3.1. based on edit, i'm 99% sure have different c() function defined in workspace/loaded somewhere in search path (getanywhere("c")$where), masking built-in version.

to test, try starting clean session (with --vanilla if possible skip reloading workspace/executing .rprofile/etc.)

if you're lucky problem in global workspace , rm("c") work -- otherwise have track down package loading booby trap ... (find("c") useful in case ...)

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
