I've just read this post: .First function in R as I have previously used the first function when instructed for a short online course in which script was shared and run through with attendees. I don't fully understand much in the post or the use of the first function (I'm a relative beginner), but I think it is related to an error message every time I try to open up a project in R studio, and the project won't open and the session won't close. I can still open the project directly from the Rproject file, but would like to get rid of this issue.
The error in the console is :
Error in ll(class = c("matrix")) : could not find function "ll"
Has something been overwritten in Rstudio? Could someone advise as to how to get rid of this?
Many thanks.
I am newbie in swift i stuck in a little problem. I am attaching image using UIImagePickerController. Good thing is that successfully attached an image but unable to get attached file name. I tried several solutions like
UIImagePickerControllerImageURL, UIImagePickerControllerImageRefrenceURL,
UIImagePickerControllerPHAsset but didn't succeeded Please guide me and thanks in advance
As per your question, you will get your point in the didFinishPickingMediaWithInfo method , where you get info object in above method in that included all info about your file.
Check below code:
let imageURL = info[UIImagePickerControllerImageURL] as! URL
print(imageURL.lastPathComponent)
Happy coding.
I am starting to use Parse and in the documentation it has examples to use the PFObject as an NSDitionary like this:
// Create the post
PFObject *myPost = [PFObject objectWithClassName:#"Post"];
myPost[#"title"] = #"I'm Hungry";
but i am getting a compiler error:
"Expected method to write dictionary element not found on object of type "PFObject"
But if I access the myPost PFObject like this, it works:
[myPost setObject:#"I'm Hungry" forKey:#"title"];
What is the problem?
I though that PFObject could be accesses as a dictionary?
thanks
I would check that you are using the latest version of the Parse SDK. This is new functionality and my guess is you haven't downloaded the SDK since this feature was introduced.
when i try your code at my side it gives me success message. I think you are using old parse library.
Thanks.
Downloading latest XCode should help. Subscript syntax is available from Xcode 4.4+
I'm making an app using the Intel Appframework MVC but I can't find a way to use transition with $.mvc.route.
I tried to combine:
$.ui.loadContent("mydiv",false,false,"pop"); //from the documentation
with the mvc in this way:
$.ui.loadContent($.mvc.route("controller/action/"+var,false,false,"pop");
The result is that the controllor run and do his job, no transition showup and from console I get this error:
Uncaught TypeError: Object #<error> has no method 'indexOf'
Does anyone have suggestion? or can you advice me about a community somewhere for this framework?
Thank you in advance
Solution from gitHub... Maybe usefull to somebody:
Call the route in this way:
$.mvc.route("controller/action/"+var+"/false/false/pop");
and then in the controller:
action:function(var1,var2,var3,var4){ $.ui.loadContent(var1,var2,var3,var4) }.
Hope could be usefull, it worked for me.
I am trying to find out the error for two days but still haven't got this unknown reason figure out.
I have configured and compiled Botan library. Everything goes ok but when try to write this sample code to be run..
S2K* s2k = get_s2k("PBKDF2(SHA-256)");
s2k->set_iterations(4049);
SecureVector<byte> key_and_IV = s2k->derive_key(48, passphrase).bits_of();
SymmetricKey key(key_and_IV, 32);
it says error: 'class Botan::PBKDF' has no member named 'set_iterations'
How can I solve this problem ?
The Botan docs for v1.11.1 report that the function get_s2k() has been deprecated, recommending that you use get_pbkdf() instead.
According to the docs, get_sdk(algospec) just returns the result of a call to get_pbkdf(algo_spec) which will give you a pointer to an instance of the class Botan::PBKDF.
First things first then, your code needs to be something more like:
PBKDF *s2k = getpbkdf("PBKDF2(SHA-256)");
Unfortunately without knowing what you want to do with s2k I can't help any further, as the docs have no reference to a public member function of PBKDF called set_iterations(). You're getting the error you mention because Botan::PBKDF really does have no member named set_iterations. You need to read the docs, work out what the purpose of set_iterations() was in your now deprecated example and hence how to achieve that purpose in the newer version of the library.
Possibly you missed your library header... as your error message says: 'has no member named...'
