1 2 3 4 5 6 7 8 9 10 11 12 13 | You can use either a selected tbl from .motus eg. "alltags", or a data.frame, instructions to convert a .motus file to all formats are below.
sql.motus <- tagme(176, new = TRUE, update = TRUE) # download and access data from project 176 in sql format
tbl.alltags <- tbl(sql.motus, "alltags") # convert sql file "sql.motus" to a tbl called "tbl.alltags"
df.alltags <- tbl.alltags %>% collect %>% as.data.frame() ## convert the tbl "tbl.alltags" to a data.frame called "df.alltags"
Create tag summaries for all tags within detection data with time in minutes with tbl file tbl.alltags
tag_site_summary <- tagSumSite(tbl.alltags, units = "mins")
Create tag summaries for only select tags with time in default hours with data.frame df.alltags
tag_site_summary <- tagSumSite(filter(df.alltags, motusTagID %in% c(16047, 16037, 16039)))
Create tag summaries for only a select species with data.frame df.alltags
tag_site_summary <- tagSumSite(filter(df.alltags, speciesEN == "Red Knot"))
