## About

[Method](/about/licenses.md)

describes a set of operations for symbolic data type based on interval-valued. The operations are processing of punctuals variables to interval variables, construction of a 3D graphic interval, linear regression interval and interval descriptive statistics such as mean, median, variance, standard deviation and mode.

## Health

[Method](/about/checks-health.md)

CRAN checks only the packages on CRAN, and it archived this one on 26 Jan 2019.

## Downloads

[Method](/about/downloads.md)

- Downloads over all time: 16,375 (It comes from CRAN alone.)

| Channel | Downloads over all time | In the total | Rank in that channel | On record |
| --- | ---: | --- | --- | --- |
| CRAN | 16,375 | yes |  | since 10 Oct 2012 |

All time is added up from the days on record for each channel.

#### Over time

Downloads over time, the last 12 whole months:

| Month | CRAN |
| --- | ---: |
| Jan 2020 | 430 |
| Feb 2020 | 69 |
| Mar 2020 | 12 |
| Apr 2020 | 15 |
| May 2020 | 13 |
| Jun 2020 | 16 |
| Jul 2020 | 14 |
| Aug 2020 | 10 |
| Sep 2020 | 10 |
| Oct 2020 | 8 |
| Nov 2020 | 11 |
| Dec 2020 | 24 |

First day on record: CRAN 10 Oct 2012.

Weeks start on Monday. A first or last week or month that the channel does not cover in full is left out, so every point is a whole period.

Days with no record add nothing to their week or month. For a little-used package that is usually a day with no downloads, but it can also be a gap in collection.

Selected function: `sdInterval`

- Kind: R function
- File: R/sdInterval.R, line 2
- Lines: 3
- Complexity: 1

Called by 4: [`summary.interval`](/cran/ISDA.R.md?fn=summary.interval&view=focus#code), [`percentileInterval`](/cran/ISDA.R.md?fn=percentileInterval&view=focus#code), [`histInterval`](/cran/ISDA.R.md?fn=histInterval&view=focus#code), [`modeInterval`](/cran/ISDA.R.md?fn=modeInterval&view=focus#code)

Calls 1: [`varianceInterval`](/cran/ISDA.R.md?fn=varianceInterval&view=focus#code)

Paths: 2 steps each way.

Called by 4:

- [`summary.interval`](/cran/ISDA.R.md?fn=summary.interval&view=focus#code)
- [`percentileInterval`](/cran/ISDA.R.md?fn=percentileInterval&view=focus#code), called by 1
  - [`summary.interval`](/cran/ISDA.R.md?fn=summary.interval&view=focus#code)
- [`histInterval`](/cran/ISDA.R.md?fn=histInterval&view=focus#code)

Calls 1:

- [`varianceInterval`](/cran/ISDA.R.md?fn=varianceInterval&view=focus#code)

The open file in the files map is `R/sdInterval.R`.

- Functions: 1
- Lines: 3
- Calls that stay inside it: 0
- Calls to other files: 1, to 1
- Calls from other files: 4, from 4

It calls: `R/varianceInterval.R` (1 call)

Called from: `R/histInterval.R` (1 call), `R/modeInterval.R` (1 call), `R/percentileInterval.R` (1 call), `R/summary.interval.R` (1 call)

| Function in sdInterval.R | Calls in other files |
| --- | --- |
| [`sdInterval`](/cran/ISDA.R.md?fn=sdInterval&view=focus#code) selected | [`varianceInterval`](/cran/ISDA.R.md?fn=varianceInterval&view=focus#code) |


3 files with no calls to or from another: `R/intervalGraph3D.R`, `R/regInterval.R`, `R/tableMulti.R`.

The whole package has 11 function names in 11 files and 11 calls between them. Most calls between files: `R/histInterval.R` and `R/interval.R` (1 call), `R/histInterval.R` and `R/sdInterval.R` (1 call), `R/interval.R` and `R/modeInterval.R` (1 call), `R/modeInterval.R` and `R/sdInterval.R` (1 call), `R/interval.R` and `R/percentileInterval.R` (1 call).

Graph: the whole call graph has 8 function names that take part in a call and 11 calls between them, set out in 4 layers with callers before what they call. 3 function names have no calls and are left out. Called by the most functions: `sdInterval` (4), `interval` (3), `varianceInterval` (2), `meanInterval` (1), `percentileInterval` (1). Calling the most functions: `summary.interval` (4), `percentileInterval` (2), `histInterval` (2), `modeInterval` (2), `sdInterval` (1).

Most connected functions: [`sdInterval`](/cran/ISDA.R.md?fn=sdInterval&view=focus#code) 5, [`summary.interval`](/cran/ISDA.R.md?fn=summary.interval&view=focus#code) 4, [`interval`](/cran/ISDA.R.md?fn=interval&view=focus#code) 3, [`percentileInterval`](/cran/ISDA.R.md?fn=percentileInterval&view=focus#code) 3, [`histInterval`](/cran/ISDA.R.md?fn=histInterval&view=focus#code) 2, [`modeInterval`](/cran/ISDA.R.md?fn=modeInterval&view=focus#code) 2

To select another function, add ?fn=NAME to this address.

The call graph also has an address of its own: /cran/ISDA.R/graph.md?fn=sdInterval&view=focus
