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).

# devtools::install_github("cont-limno/LAGOSNE", dependencies = TRUE)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.

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

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.
