In MohoWu/ricardor: Collection of plotting functions used in Ricardo projects

ricardor

ricardor contains a suite of functions that are useful for various projects at Ricardo. These functions can range from importing data, data wrangling, plotting and modelling.

Installation

You can install the development version of ricardor from Github with:

devtools::install_github("mohowu/ricardor")

Examples

Plotting functions

As HTML documents are becoming more and more popular, one advantage of HTML ouput over traditional PDF or Word is that you can embed interative plots. ricardor contains some high level plotting functions leveraging on some most popular interactive plotting packages but have the boilerplates set up for you. These functions are prefixed with plot_ for easy searching.

• plot_leaflet: Plot a leaflet map with sp object, with customisable popup text legend options.
• plot_dygraph: Plot a interactive timeseries with dygraph.
• plot_calendar: A ggplot version of calendar plot. It's easy to convert this to an interactive plot with ploty::ggplotly
• plot_polar: A polar scatter plot particular useful for plotting pollutants against wind speed and direction.

Modelling

Some functions that can be useful during modelling are prefixed with var_.

• var_shift: Shift variable(s) forward or backward by n observations to investigate if there's a delay effect between the response variable and predictor variable.
• var_select: A stepwise variable selection algorithm aiming to maximise the R2 of a multiple linear regression model.

Spatial

Some functions dealing with spatial objects are prefixed with sp_.

• sp_transform: Transform the projection system. To get code for the projection system, use projection_*.
• sp_from_data_frame: Convert data frame to spatial object.

String functions

Functions dealing with character strings are prefixed with str_.

• str_trim: Trim leading or tailing white space in a string.
• str_underscore: Replace space with "_" in a string.
• str_to_link: Convert a string to a HTML link.
