vpr_save | R Documentation |
Save VPR data as an as.oce object
vpr_save(data, metadata)
data |
a VPR data frame |
metadata |
(optional) a named list of character values giving metadata values. If this argument is not provided user will be prompted for a few generic metadata requirements. |
This function will pass a VPR data frame object to an oce
object.
Using an oce
object as the default export format for VPR data allows for
metadata and data to be kept in the same, space efficient file, and avoid
redundancy in the data frame. The function check for data parameters that
may actually be metadata parameters (rows which have the same value
repeated for every observation). These parameters will automatically be
copied into the metadata slot of the oce
object. The function will also
prompt for a variety of required metadata fields. Depending on specific
research / archiving requirements, these metadata parameters could be
updated by providing the argument metadata
.
Default metadata parameters include 'deploymentType', 'waterDepth', 'serialNumber', 'latitude', 'longitude', 'castDate', 'castStartTime', 'castEndTime', 'processedBy', 'opticalSetting', 'imageVolume', 'comment'.
