Installation Error on Windows

[RS-eco]

When I try to install the package on Windows, I get the following error message:

Warnung: Ausführung von Kommando 'curl -s -S "http://onlinelibrary.wiley.com/store/10.1002/ecy.1783/asset/supinfo/ecy1783-sup-0002-DataS1.zip?v=1&s=361647dd673d04c9b0838931cda1cf28e1f6eb1f" -o "C:\Users\mbiber\AppData\Local\Temp\RtmpkNdjTP\file2b702e22858.zip"' ergab Status 127 Error in download.file("http://onlinelibrary.wiley.com/store/10.1002/ecy.1783/asset/supinfo/ecy1783-sup-0002-DataS1.zip?v=1&s=361647dd673d04c9b0838931cda1cf28e1f6eb1f", : 'curl' call had nonzero exit status Error : unable to load R code in package 'traitdataform' ERROR: lazy loading failed for package 'traitdataform' removing 'C:/Users/mbiber/Documents/R/win-library/3.4/traitdataform' Installation failed: Command failed (1)

It seems my method of calling zipped data packages from their original source is problematic.

@MalteJochum also had problems with the installation prompting this error message:

In Maltes case it could be a Linux incompatibility with the URL provided in R/data.R.

Could you both try to execute the code blocks provided in /R/data.R and see if the demo datasets are loaded into your environment? If any error messages arise, please post them here.

I struggle to download the passerines dataset.

download.file("http://onlinelibrary.wiley.com/store/10.1002/ecy.1783/asset/supinfo/ecy1783-sup-0002-DataS1.zip?v=1&s=361647dd673d04c9b0838931cda1cf28e1f6eb1f", temp, method = "curl", quiet = TRUE)

Removing the method="curl" argument I can download the file, but than run into problems unzipping the file.

download.file("http://onlinelibrary.wiley.com/store/10.1002/ecy.1783/asset/supinfo/ecy1783-sup-0002-DataS1.zip?v=1&s=361647dd673d04c9b0838931cda1cf28e1f6eb1f", temp, quiet = TRUE)

unzip(temp, files = "Measurements of passerine birds.xlsx", exdir = ".")

Warning message: In unzip(temp, files = "Measurements of passerine birds.xlsx", exdir = ".") : requested file not found in the zip file

When removing the files argument, I still end up with an error:

unzip(temp, exdir = ".")

Warning message: In unzip(temp, exdir = ".") : internal error in 'unz' code

I have tried to manually unzip the file that I downloaded with the adapted code, but the file seems to be corrupted. So I guess the problem is still the file download from within R.

Okay. This should be solved with newest commit, which includes a dependency on package curl. Could you please try again.

[RS-eco]

The same problem still occurs.

[fdschneider]

Okay. Malte confirms the curl problem. The download.file() function uses different methods in windows and linux, and windows may use a range of download tools, that are non-standard and not automatically installed. However, I need to write this platform independent. Let's try the 'auto' method. Could you please both test the following:

temp <- tempfile(fileext = ".zip")
download.file("http://onlinelibrary.wiley.com/store/10.1002/ecy.1783/asset/supinfo/ecy1783-sup-0002-DataS1.zip?v=1&s=361647dd673d04c9b0838931cda1cf28e1f6eb1f", temp, method = "auto", quiet = TRUE, mode="wb")
unzip(temp, files = "Measurements of passerine birds.xlsx", exdir = ".")
unlink(temp)
passerines <- readxl::read_xlsx("Measurements of passerine birds.xlsx", sheet = 1)
file.remove("Measurements of passerine birds.xlsx")

[MalteJochum]

That seems to work for me.

[RS-eco]

That seems to work for me as well. ;)

[fdschneider]

Thanks for the testing. I just pushed the changes to Github. Please try if the installation works now!
