R - Generate a sequence of numbers -

-

i trying create sequences of number of 6 cases, 144 cases intervals.

like 1 example 

c(1:6, 144:149, 288:293)  1   2   3   4   5   6 144 145 146 147 148 149 288 289 290 291 292 293

how generate automatically such sequence 

seq

or function ?

i find sequence function helpful in case. if had data in structure this:

(info <- data.frame(start=c(1, 144, 288), len=c(6, 6, 6))) #   start len # 1     1   6 # 2   144   6 # 3   288   6

then in 1 line with:

sequence(info$len) + rep(info$start-1, info$len) #  [1]   1   2   3   4   5   6 144 145 146 147 148 149 288 289 290 291 292 293

note solution works if sequences you're combining different lengths.

javascript - Create websocket without connecting -

-
is there way create websocket without connecting right away? far think var ws = new websocket("ws://ws.my.url.com"); creates , connects right away. i'd create socket, define callbacks, , connect once user clicks connect button. thanks no. creating websocket means you've created connection server (or started process of connecting). there no such thing creating websocket isn't connecting yet. you create object store configuration parameters , tell object connect when wanted to, though i'm not sure why that's better creating actual websocket when connect made. or create function setup work , call function later when user clicks connect button.
