croc

The goal of croc is to allow R users to easily work with ocean colour data.

Installation

You can install croc from github with:

# install.packages("devtools")
devtools::install_github("sosoc/croc")

Example

This is a basic example to read a L3bin file and map it.

library(croc)
file <- system.file("extdata", "ocfiles", "S2008001.L3b_DAY_CHL.nc", package = "croc")
bin <- read_binlist(f)

dat <- read_compound(f)


read_compound(file,
                                           compound_vars = c("Rrs_443", "Rrs_488", "Rrs_555", "Rrs_547"))

There are helper functions to generate longitude / latitude coordinates for the bins (centre or corners). These bins are a sparse, non-rectangular, grid on a Sinusoidal projection, see

Note

An earlier version of this package imported from https://github.com/AustralianAntarcticDivision/rrshdf4 to read the old HDF4 L3bin format. This is no longer necessary, and read support is provided for the NetCDF 4.0 (HDF5) version of the files from oceandata.
