Plot all tag detections by latitude or longitude

Source : R/plotAllTagsCoord.R
plotAllTagsCoord.Rd

Plot latitude/longitude vs time (UTC rounded to the hour) for each tag using motus detection data. Coordinate is by default taken from a receivers deployment latitude in metadata.

Utilisation

plotAllTagsCoord(
  data,
  coordinate = "recvDeployLat",
  ts = "ts",
  tagsPerPanel = 5
)

Arguments

data

a selected table from motus data, eg. "alltags", or a data.frame of detection data including at a minimum variables for recvDeployName, fullID, mfgID, date/time, latitude or longitude

coordinate

column name from which to obtain location values, by default it is set to recvDeployLat

ts

column for a date/time object as numeric or POSIXct, defaults to ts

tagsPerPanel

number of tags in each panel of the plot, by default this is 5

Exemples

# 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.

# 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"))
                   
# convert sql file "sql.motus" to a tbl called "tbl.alltags"                
library(dplyr)
tbl.alltags <- tbl(sql.motus, "alltags") 

# convert the tbl "tbl.alltags" to a data.frame called "df.alltags"
df.alltags <- tbl.alltags %>% 
  collect() %>% 
  as.data.frame()

# Plot tbl file tbl.alltags with default GPS latitude data and 5 tags per panel
plotAllTagsCoord(tbl.alltags)


# Plot an sql file tbl.alltags with 10 tags per panel
plotAllTagsCoord(tbl.alltags, tagsPerPanel = 10)


# Plot dataframe df.alltags using receiver deployment latitudes with default
# 5 tags per panel
plotAllTagsCoord(df.alltags, coordinate = "recvDeployLat")


# Plot dataframe df.alltags using LONGITUDES and 10 tags per panel
# But only works if non-NA "gpsLon"!
if (FALSE) plotAllTagsCoord(df.alltags, coordinate = "gpsLon", tagsPerPanel = 10)
# Plot dataframe df.alltags using lat for select motus tagIDs
plotAllTagsCoord(filter(df.alltags, motusTagID %in% c(19129, 16011, 17357)), 
                 tagsPerPanel = 1)
