USelection2016.Instagram: Hourly time series of the number of candidate-related media...

In WaveletComp: Computational Wavelet Analysis

Description

One week (Sunday, 2016-10-30 23:00:00 EDT through Sunday, 2016-11-06 23:00:00 EST; 170 hours) of hourly readings of the number of media posted on Instagram, supposedly (according to hashtags with which they were annotated) positive/neutral or in opposition towards candidates Trump and Clinton. The 2016 US presidential election took place on Tuesday, 2016-11-08.

Usage

data("USelection2016.Instagram")

Format

A data frame of four columns:

	date	:	hour of measurement (in EST5EDT, Eastern Time Zone),
			format: "%F %T"
	trump.pos	:	number of media uploads with hashtag suggesting
			positive/neutral annotation to Trump
	clinton.pos	:	number of media uploads with hashtag suggesting
			positive/neutral annotation to Clinton
	trump.neg	:	number of media uploads with hashtag suggesting
			negative annotation to Trump
	clinton.neg	:	number of media uploads with hashtag suggesting
			negative annotation to Clinton

Details

Media posted on Instagram are usually annotated with hashtags. A hashtag can be used to determine whether a candidate-related posting is positive/neutral towards a candidate (for example, #makeamericagreatagain for Trump, #hillary2016 for Clinton) or opposing a candidate (for example, #dumptrump for Trump, #neverhillary for Clinton). In this way, four hourly time series are obtained: Trump vs. Clinton, supporters vs. opponents. For further details, see the reference below. The date column also contains a label EDT (Eastern Daylight Time) or EST (Eastern Standard Time); daylight saving time ended 2016-11-06 at 1:00 a.m. when clocks were moved back to 1:00 a.m. EST. The time stamp "2016-11-06 02:00:00" therefore occurs twice, once with EDT and once with EST.

Source

Hourly readings of the number of media posted on Instagram were collected using Instagram's built-in API.
