This function tries to search for an API Key





An AIMS Data Platform API Key


Either a character vector API Key found in .Renviron or, if missing entirely, an error message.


The AIMS Data Platform R Client provides easy access to data sets for R applications to the AIMS Data Platform API. The AIMS Data Platform requires an API Key for requests, which can be obtained at this link. It is preferred that API Keys are not stored in code. We recommend storing the environment variable AIMS_DATAPLATFORM_API_KEY permanently under the user's .Renviron file in order to load the API Key automatically.

There are two types of data currently available through the AIMS Data Platform API: Weather and Sea Water Temperature Loggers. They are searched internally via unique DOI identifiers. Only one data type at a time can be passed to the argument target.

A list of arguments for filters can be exposed for both Weather and Sea Water Temperature Loggers using function aims_expose_attributes.

Note that at present the user can inspect the range of dates for the temperature loggers data only (see usage of argument summary in the examples below). For that, the argument summary must be either the string "summary-by-series" or "summary-by-deployment". In those cases, time filters will be ignored.

Details about available dates for each dataset and time series can be accessed via Metadata on AIMS Data Platform API. We raise this caveat here because these time boundaries are very important; data are collected at very small time intervals, a window of just a few days can yield very large datasets. The query will return and error if it reaches the system's memory capacity.

For that same reason, from version 1.1.0 onwards, we are offering the possibility of downloading a mean daily aggregated version. For that, the user must set summary = "daily". In this particular case, query filter will be taken into account.
