LAGOSNE

The LAGOSNE package provides an R interface to download LAGOS-NE data, store this data locally, and perform a variety of filtering and subsetting operations.

LAGOS-NE contains data for 51,101 lakes and reservoirs larger than 4 ha in 17 lake-rich US states. The database includes 3 data modules for: lake location and physical characteristics for all lakes; ecological context (i.e., the land use, geologic, climatic, and hydrologic setting of lakes) for all lakes; and in situ measurements of lake water quality for a subset of the lakes from the past 3 decades for approximately 2,600-12,000 lakes depending on the variable (see Soranno et al. 2017 below).

Installation

# install stable version from CRAN
install.packages("LAGOSNE")

# install development version from Github
# install devtools if not found - install.packages("devtools")
# devtools::install_github("cont-limno/LAGOSNE", dependencies = TRUE)

Data

The lagosne_get function downloads the LAGOSNE files corresponding to the specified version from the EDI data repository. Files are stored in a temporary directory before being “compiled” to an R data format in the location specified by the dest_folder argument. Recommended setting is lagos_path(). Data only needs to be downloaded one time per version per machine. Each LAGOSNE module has a unique version number. However, only the limno module has been dynamically updated. Therefore the LAGOSNE R package uses the limno module version number to check-out specific datasets. The latest version of the LAGOSNE dataset is 1.087.3.

library(LAGOSNE)
lagosne_get(dest_folder = lagos_path())

Usage

Load Package

library(LAGOSNE)

Load data

The lagosne_load function returns a named list of data.frame objects. Use the names() function to see a list of available data frames names(dt).

Select data

lagosne_select is a convenience function whose primary purpose is to provide users with the ability to select subsets of LAGOS tables that correspond to specific keywords (see LAGOSNE:::keyword_partial_key() and LAGOSNE:::keyword_full_key()). See here for a comprehensive tutorial on generic data.frame subsetting.

Legacy Versions

R Package

To install versions of LAGOSNE compatible with older versions of LAGOS-NE run the following command where ref is set to the desired version (in the example, it is version 1.087.1):

# install devtools if not found
# install.packages("devtools")
devtools::install_github("cont-limno/LAGOSNE", ref = "v1.087.1")
