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.

Utilisation

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.

Détails

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.

Exemples


# download and access data from project 176 in sql format
# usename and password are both "motus.sample"
if (FALSE) sql.motus <- tagme(176, new = TRUE, update = TRUE)

# OR use example sql file included in `motus`
sql.motus <- tagme(176, update = FALSE, 
                   dir = system.file("extdata", package = "motus"))
  
# Access 'activity' table
library(dplyr)
#> 
#> Attachement du package : ‘dplyr’
#> Les objets suivants sont masqués depuis ‘package:stats’:
#> 
#>     filter, lag
#> Les objets suivants sont masqués depuis ‘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)
