Package TSclust in R, What is the definition of SAX.breakpoints.table function -


there function called mindist.sax in package tsclust. here body of function:

require(tsclust) > mindist.sax function (x, y, alpha, n)  {     w <- length(x)     symb <- sax.breakpoints.table(alpha)     d <- 0     (i in 1:w) {         xi <- x[i]         yi <- y[i]         if (abs(xi - yi) > 1) {             d <- d + (symb[max(xi, yi)] - symb[min(xi, yi) +                  1])^2         }     }     sqrt((n/w) * d) } <environment: namespace:tsclust>

as can seen above, there function called sax.breakpoints.table has been re-called.

i need know exact definition of function (i.e. sax.breakpoints.table). tried sax.breakpoints.table 

> sax.breakpoints.table error: object 'sax.breakpoints.table' not found

as as:

> ls("package:tsclust")  [1] "cluster.evaluation"    "convert.to.sax.symbol" "diss"                  "diss.acf"               [5] "diss.ar.lpc.ceps"      "diss.ar.mah"           "diss.ar.pic"           "diss.cdm"               [9] "diss.cid"              "diss.cor"              "diss.cort"             "diss.dtwarp"           [13] "diss.dwt"              "diss.eucl"             "diss.frechet"          "diss.int.per"          [17] "diss.mindist.sax"      "diss.ncd"              "diss.pacf"             "diss.pdc"              [21] "diss.per"              "diss.pred"             "diss.spec.glk"         "diss.spec.isd"         [25] "diss.spec.llr"         "loo1nn.cv"             "mindist.sax"           "paa"                   [29] "pvalues.clust"

but couldn't find it!

>tsclust:::sax.breakpoints.table function (n)  {     qnorm(0:n/n) } <environment: namespace:tsclust>

this question, view source code in r, viewing function within package, hidden ones.

hope helps

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...
