DAM loading works on windows 10 but not ubuntu 20.04

[IllustratedMan-code]

When I run my code in windows everything works fine but when I try to run the same code in ubuntu (with directories changed accordingly) I get this error: Error in parse_datetime(stop_datetime, tz = tz) : Unexpected type for x It seems to have something to do with the as.character conversion but I don't really know. Any ideas?

[IllustratedMan-code]

I just tested it with the toy data as well. I get the same error.

[qgeissmann]

any chance you can actually put the code you are trying to run with the toy data?

[IllustratedMan-code]

I did not even have the toy data downloaded when I got the error.

[IllustratedMan-code]

And I kept the toy data and test code isolated in it's own folder

[qgeissmann]

I mean, I cannot help unless you provide an example of code that does fail... ideally, somethine I can reproduce (e.g. with minimal data, or uding the package's data)

[IllustratedMan-code]

library(damr)
setwd("/home/david/Documents/R/damr_tutorial")
list.files()
m <- fread("metadata.csv")
metadata <- link_dam_metadata(m, result_dir = "/home/david/Documents/R/damr_tutorial")
data <- load_dam(metadata)

print(data)

This is my test code with the sample data list.files() outputs "metadata.csv" "Monitor11.txt" "Monitor14.txt" "Monitor64.txt" Thank you for all your help so far.

[qgeissmann]

And the error is on load_dam()?, or before onlink_dam_metadata()? Are you just using the data from the tutorial, or your own, or have you changed anything? Same question for the metadata. what is the result of print(m) , if possible, what is the result of print(metadata). thanks!

[IllustratedMan-code]

The error is on load_dam(). This is just the data from the tutorial. I have not changed anything. I am going to go ahead and copy the results of print(m) and print(metadata)

[IllustratedMan-code]

Sorry about the formatting, not the best githubber

[IllustratedMan-code]

Here is the windows 10 code (that works). The only difference is the directory

library(damr)
setwd("C:/Users/dalew/OneDrive/Documents/BioResearch/Rethomicstester")
list.files()
m <- fread("metadata.csv")
metadata <- link_dam_metadata(m, result_dir = "C:/Users/dalew/OneDrive/Documents/BioResearch/Rethomicstester")
data <- load_dam(metadata)
print(data)

[qgeissmann]

can you print str(metadata). So far, it looks like the time, in your metadata file is not the right format as expected...

[qgeissmann]

can you try to explicitly convert your IDate to a POSIXct:

metadata[ , stop_date :=  as.POSIXct(stop_datetime)]
str(metadata)
load_dam(...)

[IllustratedMan-code]

So it works if I did your command as metadata[ , stop_datetime := as.POSIXct(stop_datetime)] rather thanmetadata[ , stop_date := as.POSIXct(stop_datetime)] The other way gave me the same error.

[IllustratedMan-code]

Any idea why I have to make this conversion on linux but not windows?

[qgeissmann]

a yes, sorry that was a typo on my side. so we have a patch for now...? and then I can force that to happen internally in your case...

[IllustratedMan-code]

Yep. Everything seems to work after making the conversion.

[qgeissmann]

marked as fixed, not yet on CRAN, but should work on the github version of the package as of today
