It creates time series with the absolute frequency of one or more terms, in one or more websites.

ShowAbsoluteTS(terms, dataset, type = "graph", specificWebsites = NULL,
  startDate = NULL, endDate = NULL, rollingAverage = 31,
  align = "center", verticalLine = NULL, smoothLine = FALSE,
  customTitle = NULL, export = FALSE, project = NULL,
  website = NULL)

Arguments

terms

A character vector with one or more words to be analysed.

dataset

A `castarter` dataset.

type

Type of output: either "graph" (default) or "data.frame".

specificWebsites

Character vector of the names of one or more websites included in the corpus. Only selected websites will be included in the analysis.

startDate

Character vector with date in the format year-month-date, e.g. "2015-07-14". Given dates are included, e.g. if you wish to include all of 2015, set startDate="2015-01-01", endDate"2015-12-31")

endDate

Character vector with date in the format year-month-date, e.g. "2015-07-14". Given dates are included, e.g. if you wish to include all of 2015, set startDate="2015-01-01", endDate"2015-12-31")

rollingAverage

Integer, defaults to 31. Number of days used to calculate word frequency as shown in the time series. Time series shows word frequency for each date as an average of the N number of days (N=rollingAverage) around the given date. If align = "centre", and rollingAverage = 31, this means that the value for each day corresponds to the average value for the given day, the 15 days before it, and the 15 days after it.

align

Defaults to "center", can be either "left", "right" or "center" and refers to the way the rolling average is calculated.

verticalLine

Defaults to NULL. Draws a vertical dotted line at the date provided. If given, value must correspond to one or more dates in the YMD format, e.g. "2016-08-17".

smoothLine

Logical, defaults to FALSE. If TRUE draws a smooth line over the time series.

customTitle

A character vector, defaults to NULL. If provided, it overrides default graph title.

export

Logical, defaults to FALSE. If TRUE, saves the time series in both png and pdf format. If project and website are provided, in saves the timeseries in the "Outputs" subfolder.

project

Name of 'castarter' project. Must correspond to the name of a folder in the current working directory.

website

Name of a website included in a 'castarter' project. Must correspond to the name of a sub-folder of the project folder.
