Download or resume a download of the 'nodeData' table in an existing Motus database. nodeData contains information regarding the 'health' of portable node units.

Usage

nodeData(src, resume = FALSE)

Arguments

src

SQLite connection. Result of tagme(XXX) or DBI::dbConnect(RSQLite::SQLite(), "XXX.motus").

resume

Logical. Resume a download? Otherwise the table is removed and the download is started from the beginning.

Details

This function is automatically run by the tagme() function with resume = TRUE.

If an nodeData table doesn't exist, it will be created prior to downloading. If there is an existing nodeData table, this will update the records.

Note that only records for CTT tags will have the possibility of nodeData.

Node metadata is found in the nodeDeps table, updated along with other metadata.

Examples

# Download sample project 176 to .motus database (username/password are "motus.sample")
if (FALSE) sql_motus <- tagme(176, new = TRUE)

# Or use example data base in memory
sql_motus <- tagmeSample()
  
# Access `nodeData` table
library(dplyr)
a <- tbl(sql_motus, "nodeData")
  
# If you just want to download `nodeData`
if (FALSE) my_tags <- nodeData(sql_motus)
