You should be sure you do not have packrat autoloader enabled in your .Rprofile for your project.

Thanx, that worked! Really appreciate the quick response!

Now I have trouble with loading .RData file.

I have placed Data.RData in Data\\Data.RData and use load("Data\\Data.RData", envir=.GlobalEnv). It works when running locally, but crashes on the server.

Any suggestions?

[Jon Arne Heskje]

And the code is placed in server.R. I have tried both outside and inside shinyServer function.

[Andy Kipp]

You should use single forward slashes instead of double backslashes.

[Jon Arne Heskje]

Have changed that, but still doesn't work.

I get following in chrome (the adress is https://gabler.shinyapps.io/Knekkpunktanalyse/:

An error has occurred

The application failed to start.

Warning in readChar(con, 5L, useBytes = TRUE) : cannot open compressed file '.\Data\Bedrift.RData', probable reason 'No such file or directory' Error in value[[3L]](cond) : cannot open the connection Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous> Execution halted

In the console I get:

[Tareef Kawaf]

Hi Jon,

You will want to switch those from .\Data\Bedrift.RData to ./Data/Bedrift.RData

[Jon Arne Heskje]

I know, and I have done that. I still get the error-message which I have posted above.

[Jon Arne Heskje]

Hi Andy,

Could you help me with the load() function??

I have the following code in server.R:

load("Data/Bedrift.RData")

This works when running locally on my computer, but not when published on the shiny server. 

Any suggestions??

You should double check that you're using forward slashes (the URL you posted above still shows back slashes in the error message).

You should also check that the case of your file names and directories match EXACTLY. Shinyapps.io runs on linux and file names are case sensitive.

[Jon Arne Heskje]

That's what I think is funny. I am writing:

load('Data/Bedrift.RData')

which has forward slashes, but the error-message is with back slashes. Why??

[Andy Kipp]

That does sound strange. Did you re-deploy your application after making the changes? 

By chance did you have the load statement duplicated in a different file?

I'm getting a very strange behaviour now.

If you  check this url https://gabler.shinyapps.io/Knekkpunktanalyse/  you'll see that the page is loading. But, it don't get any of the graphs...

I get the following warning message in my console after deployApp()

Warning message:

Error detecting locale: Error in read.table(file = file, header = header, sep = sep, quote = quote, : incomplete final line found by readTableHeader on 'raw'

 (Using default: en_US) 

???? I'm really confused!

[Jon Arne Heskje]

Is this the same problem as in previous question here on Groups? https://groups.google.com/forum/#!topic/shinyapps-users/Fuh74H78G4s

When running rsconnect:::systemInfo() I get:

Error in read.table(file = file, header = header, sep = sep, quote = quote,  : 

  incomplete final line found by readTableHeader on 'raw'

This seems to me to be similar as the guy feidherbard in the url above.

My sessionInfo() is:

R version 3.2.1 (2015-06-18)

Running under: Windows 8 x64 (build 9200)

attached base packages:

Really appreciate the help!!

[Andy Kipp]

I don't think the warning is the issue at hand here perse. When I view the javascript console for your application, I see a bunch of syntax errors which lead me to believe there might be an encoding problem with your data. Is your data UTF-8 encoded?

[Jon Arne Heskje]

Yes, I need it to be UTF-8 so I can write norwegian letters...

jonarne

[Jon Arne Heskje]

And, just so you know, I have just written the needed data "by hand" into the script and deployed it. So, it will change the script that is used.

But, my guess is that the UTF-8 will still stop this???

-jonarne

[Jon Arne Heskje]

I have just changes the encoding to ISO-8859-1 (System default). Still get the same error. 

Have also dropped using load() and have manually written in the data needed.

-jonarne

[Jon Arne Heskje]

I have discovered the error.

I am using scandinavian letters (æøå) and have set the encoding to UTF-8 (by 'Save with encoding'). 

This still mess up the highchart widget (using java). So, when I deleted all scandinavian letters inside highchart-codes it works!

But I still get the warning message:

Warning message:

Error detecting locale: Error in read.table(file = file, header = header, sep = sep, quote = quote, : incomplete final line found by readTableHeader on 'raw'

 (Using default: en_US) 

jonarne

[Andy Kipp]

Jon,

I wouldn't worry about the warning, our locale detection code isn't perfect right now (especially on Windows). If you need override the locale string from the default (en_US) you can use:

options(rsconnect.locale = 'your_locale')

Could you include the error you are getting and whether you have tried out Andy's suggestion?
