Add/update batch activity — activity • motus

Download or resume a download of the activity table in an existing Motus database. Batch activity refers to the number of hits detected during a given batch. Batches with large numbers of hits may indicate interference and thus unreliable hits.

Usage

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

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 'activity' table
library(dplyr)
#> 
#> Attaching package: ‘dplyr’
#> The following objects are masked from ‘package:stats’:
#> 
#>     filter, lag
#> The following objects are masked from ‘package:base’:
#> 
#>     intersect, setdiff, setequal, union
a <- tbl(sql_motus, "activity")
  
# If interrupted and you want to resume
if (FALSE) my_tags <- activity(sql_motus, resume = TRUE)
