ltertools
- Tools Developed by the Long Term Ecological Research CommunityThe goal of ltertools
is to centralize the R functions created by members of the Long Term Ecological Research (LTER) community. Many of these functions likely have broad relevance that expands beyond the context of their creation and this package is an attempt to share those tools and limit the amount of “re-inventing the wheel” that we each do in our own silos.
The conceptual theme of functions in ltertools
is necessarily broad given the scope of the community we aim to serve. That said, the identity of this package will likely become more clear as we accrue contributed functions. In the meantime, please do not hesitate to add or request a function for fear that it doesn’t “fit” this package. That may eventually become a concern but at this stage we are aiming to house all extant functions regardless of their relatedness to one another.
You can install the development version of ltertools
from GitHub with:
As functions are added to the package they will be briefly summarized below and attributed to their author(s)
begin_key
– creates the first two columns of a ‘column key’ and–if the optional guess_tidy
argument is set to TRUE
–“guesses” at what the tidy names ‘should be’
harmonize
– performs column key-based harmonization. We strongly recommend using the begin_key
to start the creation of a column key to make sure the formatting requirements of this function are met
read
– Reads in all files of specified types in a particular folder and stores them as elements in a list. List element names are the respective file names. Currently supports CSV, TXT, XLS, and XLSX file formats
cv
– Calculate coefficient of variation (CV) from a vector of numbers
convert_temp
– Convert temperature values from one set of units to another
site_timeline
– Create a timeline of sites that meet user-specified site code and/or habitat criteria. Uses built in lter_sites
data object that includes much useful site informationSee CONTRIBUTING.md
for specifics but at a glance:
To contribute one of your functions in exchange for authorship credit: open a GitHub issue
To suggest minor fixes or point out bugs: open a GitHub issue
To implement major / structural changes: fork the repository, add your content to the dev
folder, and open a pull request when you are finished
ltertools
will maintain a consistent “feel” and style of functions but we (the maintainers) are happy to perform these edits on your behalf. If you’d like to take care of this yourself (completely optional!) you are welcome to do so. Please see CONTRIBUTING.md
for a specific style guide.
If you would like to contribute a function that is similar to a function that already exists in ltertools
please do not hesitate! In the event that this happens, the following steps will be followed:
The functions will be combined to preserve the earlier function’s elements while expanding to include the maximum number of novel features (i.e., arguments / options)
Both function authors will be credited in the combined function’s description and in this README (see above)
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
