In pegoraro/qchlorophyll: qchlorophyll

A brute force approach is used to match latitude and longitude pairs and the corrisponding value of variable.

1 2	format_lon_lat(dataframe, reference_df, variable, lon_lat_names = c("lon", "lat"))

`dataframe`	a dplyr dataframe.
`reference_df`	a reference dataframe that must contain at least longitude and latitude. A dataframe.
`variable`	variable to be used in the reformatting process. The values of this variable will be reordered according to the new longitude and latitude values. Character.
`lon_lat_names`	name of longitude and latitude variables. A character vector. Example: by default lon_lat_names = c("lon", "lat")
