recordTable function using data sheet generated from Timelapse software

[Nor Bazilah Razali]

Hi all, 

Is it possible to use the recordTable function to generate a species table using the data sheet generated from Timelapse software? I've attached the sample data from Timelapse data sheet for you to look over. 

Thanks for any help, much appreciated

Regards,

Hi,

I would be interested to get this answer as well! I have annotated my data on the Timelapse software too, but I am not sure it is in the same output format of the recordTable function.

Hi Nadia,

Recently, I figured out how to extract data from the Timelapse datasheet using filterRecordTable (Filter species record table for temporal independence). First, you need to install these packages to enable the filterRecordTable function:

install.packages("remotes") # if not installed
install.packages("R.rsp")   # if not installed
remotes::install_github("jniedballa/camtrapR", build_vignettes = TRUE)

Then,  you make the timelapse datasheet from csv format to data frame using data.frame function. Afterward, you tally the speciesCol, stationCol, and recordDateTimeCol according to  Timelapse Datasheet. Mine might be different than yours.

Below are the scripts I manage to make R run the filterRecordTable.

timelapse <- read.csv("BRCT33.csv")

dftimelapse <- data.frame(timelapse)

rec_table_filt <- filterRecordTable(recordTable         = dftimelapse,
                                    speciesCol          = "Species",
                                    stationCol = "CamtrapID",
                                    recordDateTimeCol   = "DateTime",
                                    minDeltaTime        = 60,
                                    deltaTimeComparedTo = "lastIndependentRecord")

table(rec_table_filt$Species)

Hope it helps.

Best Regards,

Bazilah

Hello, 

The tables from Timelapse can be used directly, so they already are record tables and there is no need to convert anything. filterRecordTable is an optional step.

One can also proceed with detectionHistory (if occupancy analyses are the aim). 

In that case one needs to adjust speciesCol, stationCol and dateTimeCol, and possibly adjust dateTimeFormat.

Best regards,

Jürgen
