NOTE The Neotoma R package accesses the Windows-based API for the database. This API is being deprecated, but is still available. Due to changes in the database servers, the API Help is no longer functioning. Links to API help have been left, but do not resolve.
neotoma package is a programmatic R interface to the Neotoma Paleoecological Database. The package is intended to both allow users to search for sites and to download data for use in analyical workflows of paleoecological research.
For more information on the package please refer to:
Goring, S., Dawson, A., Simpson, G. L., Ram, K., Graham, R. W., Grimm, E. C., & Williams, J. W.. (2015). neotoma: A Programmatic Interface to the Neotoma Paleoecological Database. Open Quaternary, 1(1), Art. 2. DOI: 10.5334/oq.ab
For ongoing news, issues or information please join the Neotoma Slack server (and add the #r channel). Slack is a real time chat application and collaboration hub with mobile and desktop applications.
We welcome contributions from any individual, whether code, documentation, or issue tracking. All participants are expected to follow the code of conduct for this project.
Package functions resolve various Neotoma APIs and re-form the data returned by the Neotoma database into R data objects. The format of the Neotoma data, and the actual API functions can be accessed on the Neotoma API website.
If you have used the package please consider providing us feedback through a short survey.
More functions are available through the package help. These represent the core functions:
get_site- obtain information on sites in the Neotoma dataset (which may contain multiple datasets). API
get_dataset- obtain dataset metadata from Neotoma. API
get_download- obtain full datasets (pollen or mammal) from Neotoma. API
compile_list- using established pollen-related taxonomies from the literature, take the published taxon list and standardize it to allow cross site analysis.
get_contact- find contact information for data contributors to Neotoma. API
get_publication- obtain publication information from Neotoma. API
get_table- return matrices corresponding to one of the Neotoma database tables. tables
get_taxa- Get taxon information from Neotoma. API
get_chroncontrol- Get chronological information used to build the age-depth model for the record. API
get_closest(); Changed character encoding for two data tables,
taxon.list, made them available in the main package using
get_dataset(gpid=123)was returning an error, fix corrects the error to allow unassigned
xvariables. Updated the allowable dataset types for searching to reflect the larger set of dataset types within Neotoma.
get_dataset()functions so that a vector of dataset or siteids can be passed to improve more general workflow methods.
taxa()function to easily extract taxa from one or multiple download objects.
compile_download(), single sample downloads were failing to compile properly, added the
taxa()function to extract taxa lists from large download objects.
plot_leaflet()to allow interactive exploration of downloaded Neotoma data. Integrates with the Neotoma Explorer. Minor bugfix for
get_download()to allow records to be sent to Neotoma and to be filtered.
plot()method based on tests against Tilia files in the Neotoma Holding Tank & built more robust interpolation in
read_bacon()so that age models without interpolated dates can still be imported.
browse()now opens multiple datastes in the Neotoma Explorer at once.
Stratiplot()method, using the
analoguepackage to plot dataset diagrams from
download_listobjects, bug fixes for
write_agefile()and a new function,
read_bacon(), to read in and integrate Bacon chronologies into
gpidselection. Added a
get_closest()function to find the closest sample site. Mostly clean-up of reported bugs by users. Revised examples for faster check speed.
get_dataset()for site level data to account for some datasets with empty submission data. Some style changes to code (non-functional changes)
read.tilia()added to read Tilia (http://tiliait.com) style XML files. Moved to using
jsonliteto support parsing.
get_geochron()to address bug reports and improve object
plot()method for datasets, sites & downloads. Fixed a bug with records missing chronologies.
# Example requires the mapdata package: library('mapdata') # You may use either '%' or '*' as wildcards for search terms: test <- get_dataset(taxonname='Mammuthus*') The API call was successful, you have returned 3273 records. site.locs <- get_site(test) # A crude way of making the oceans blue. plot(1, type = 'n', xlim=range(site.locs$long)+c(-10, 10), ylim=range(site.locs$lat)+c(-10, 10), xlab='Longitude', ylab = 'Latitude') rect(par("usr"),par("usr"),par("usr"),par("usr"),col = "lightblue") map('world', interior=TRUE, fill=TRUE, col='gray', xlim=range(site.locs$long)+c(-10, 10), ylim=range(site.locs$lat)+c(-10, 10), add=TRUE) points(site.locs$long, site.locs$lat, pch=19, cex=0.5, col='red')
# Requires ggplot2 library('ggplot2') library('plyr') pubs <- get_publication() pub.years <- ldply(pubs, "[[", "meta") ggplot(data=pub.years, aes(x = year)) + stat_bin(aes(y=..density..*100, position='dodge'), binwidth=1) + theme_bw() + ylab('Percent of Publications') + xlab('Year of Publication') + scale_y_continuous(expand = c(0, 0.1)) + scale_x_continuous(breaks = seq(min(pub.years$year, na.rm=TRUE), 2014, by=20))
