nstandr

A package that does (Organizational) Names STANDardization in R.

nstandr reproduces procedures described in Thoma et al. (2010), Magerman et al. (2006), Cockburn et al. (2009), Wasi & Flaaen (2015) and more.

Installation

devtools::install_github("stasvlasov/nstandr")

Usage

The package provides its main function standardize. The function expect character vector of organization names as input and returns its standardized version.

For the standardization methods described in Magerman et al. (2006) and Cockburn et al. (2009) you can use standardize_magerman and standardize_cockburn respectively. These functions are similar to standardize(x, procedures=nstandr:::magerman_procedures_list)) and standardize(x, procedures=nstandr:::cockburn_procedures_list)) but with additional options for tweaking original procedures and with more documentation.

Here is an example of standardize_magerman usage
