QUESTION
I would greatly appreciate any feedback you might offer regarding the issue I am having with my Word Prediction Shiny APP Code for the JHU Capstone Project.
My UI code runs correctly and displays the APP. (see image and code below)
Challenge/Issue: My problem is that after entering text into the "Text input" box of the APP, my server.R code does not return the predicted results.
Prediction Function:
When I run this line of code in the RConsole -- predict(corpus_train,"case of") -- the following results are returned: 1 "the" "a" "beer"
When I use this same line of code in my server.r Code, I do not get prediction results.
Any insight suggestions and help would be greatly appreciated.

Hello I am working on a problem with scala/spark project trying to do some computation my scala code works well on spark-shell but when try to run the same code with sbt-assembly to convert scala to .jar file, I face this error:
Unable to find encoder for type AccessLog. An implicit Encoder[AccessLog] is needed to store AccessLog instances in a Dataset. Primitive types (Int, String, etc) and Product types (case classes) are supported by importing spark.implicits._ Support for serializing other types will be added in future releases.
I am trying to convert Dataset[List[String]] to be Dataset[AccessLog] AccessLog is a case class, by mapping it using.
The code that generates the error:

I have a list of list, and each sublist also have multiple df. Now I would like to know the number of cols in each df in each sublist using imap
. How can I get point to the df correctly.
Sample list can be built using:

Answered 2021-May-26 at 14:15You can map_depth
to great advantage. You just have to assign a value to .depth
argument so the function will be applied as many levels deep as you specified. In order to have a nicer looking output I just made 2 modifications:

I have a list of list and I would like to input them into muti excel files, wherer excel name will be the sublist name, and name of each sheet in the excel will be the df name in each sublist. I tried to utilize imap
and map
to reach my goal. However I am new to those and still confuse how to set it up correctly.
The sample list can be build using

Answered 2021-May-25 at 22:29We just need a simple tweak to the code
- If we are using multiple expressions, block it inside the

. I understand that all cols in lst
will be charters and won't be able to used again for analysis. But that is what I want. How should I do that?
ANSWER
Answered 2021-May-21 at 17:44For these sort of problems where you need to map names to names, I like to use named vectors (with the function setNames()
) the way you would use dictionaries in python. Then you can use it to extract the vector of labels that you want to prepend to each data.frame.

I try to write a function to filter a list that has muti df by ID and then add label to each dataset. However my codes did not work. Could anyone take a look of my codes and give me some guidance on what I did wrong? I am not that good working with list using map

My codes are:
