Title
webchem: An R Package to Retrieve Chemical Information from the Web
Subject
ecotoxicology, chemistry, data cleaning, web scraping, rOpenSci.
Description
A wide range of chemical information is freely available online, including identifiers,
experimental and predicted chemical properties. However, these data are scattered over
various data sources and not easily accessible to researchers. Manual searching and downloading of such data is time-consuming and error-prone. We developed the open-source R
package webchem that allows users to automatically query chemical data from currently
14 web sources. These cover a broad spectrum of information. The data are automatically
imported into an R object and can directly be used in subsequent analyses. webchem enables easy, structured and reproducible data retrieval and usage from publicly available
web sources. In addition, it facilitates data cleaning, identification and reporting of substances. Consequently, it reduces the time researchers need to spend on chemical data
compilation
