rpys {BibPlots} R Documentation

## Create a spectrogram using data from the free software CRExplorer

### Description

Provide the contents of the CSV (Graph) file from the 'CRExplorer' in a data frame, e.g. df, and the function call rpys(df, py1, py2) creates the spectrogram. Here, py1 and py2 are the lowest and highest publication year to be used in the plot. The function rpys takes some optional arguments to modify its behaviour, see arguments and details.

### Usage

rpys(
df,
py1 = min(df$Year), py2 = max(df$Year),
col_cr = "red",
col_med = "blue",
smoothing = TRUE,
par_pch = 20,
plot_NCR = TRUE,
plot_Med = TRUE,
...
)


### Arguments

 df data frame with reference publication year, number of cited references, and median deviation as exported from the CRExplorer (File > Export > CSV (Graph)). py1 determines lowest reference publication year which should be shown in the graph (optional parameter). py2 determines highest reference publication year which should be shown in the graph (optional parameter). col_cr character color name value to determine color of the line and points of the number of cited references (optional parameter). The default value is "red". col_med character color name value to determine color of the line and points of the median deviation (optional parameter). The default value is "blue". smoothing boolean variable (optional parameter) which determines if the lines of the spectrogram are smoothed or not. (T: yes apply smoothing, F: no do not apply smoothing). The default value is T. par_pch integer value to set the point type (optional parameter). The default value is 20. plot_NCR boolean variable (optional parameter) which determines the NCR curve should be plotted. plot_Med boolean variable (optional parameter) which determines the median deviation curve should be plotted. ... additional arguments to pass to the plot, points, and lines functions.

### Details

rpys(df=data_frame, py1=integer_value, py2=integer_value, smoothing=boolean, col_cr=character_color_name, col_med=character_color_name, par_pch=integer, plot_NCR=boolean, plot_Med=boolean, ...) Only the argument df is necessary. All other aruments are optional.

An example data frame is provided as rpys_example_data in the package. It can be used to create an example spectrogram.
