            Using autoplotly in shiny app with user selected columns
            Asked 2021-Jun-14 at 07:56

            I am making a shiny app that allows the user to upload a CSV, then select the independent and dependent variables. Right now I am able to upload a file, select variables and run regression analysis. But, I am stuck at the step where I would pass the lm object to autoplot then making it interactive via autoplotly in a new tab. How can I create interactive regression plots via using user selected variables in a shiny app?

            What are your preferred techniques for combining a table with a plot in one image using R? I remember using tableGrob() and either patchwork or cowplot months ago but cannot remember the details.

            This example uses the ggstatsplot package. I would like to add the correlation coefficients to the correlogram (correlation plot).

            The key elemnent is tableGrob() from gridExtra package!

            We could use grid.arrange().

            For the table use tableGrob() to create a table like the plot of a data frame. Then you can use it with grid.arrange() function.

            tuneGrid not working properly in neural network model
            Asked 2021-Apr-27 at 07:42

            I am wanting to build a neural network classifier using the caret package. I have specified a tunegrid with some hyper-parameters that I want to test to get the best accuracy.

            After I run the model, the train function function will always default to the standard decay and size values. Is this a bug within caret? or is there an issue with my code?

            ANSWER

            Answered 2021-Apr-27 at 07:42

            You provided the wrong argument, it should be tuneGrid = instead of tunegrid = , so caret interprets this as an argument for nnet and selects its own grid

            With the grid you see above, caret will choose the model with the highest accuracy and from the results provided, it is size=5 and decay=0.1, with the highest accuracy of 0.318.

            To do it with the grid you defined,using an example:

            Having problems with linear pytorch model initialization
            Asked 2021-Apr-14 at 21:52

            I am trying to figure out what is wrong with my initialization of the neural network model. I have already set a pdb trace to see that the defining neural network part is the source of error. Also, I get yellow marks on the defining neural network code because the module is expected to be returned but if I return the module, it causes a recursion error. It is a linear model that has to have an input dimension of the batch size * 81 and an output dimension of the batch size * 1. I am relatively new at pytorch and defining deep neural networks so this may not be a good question. My syntax may also be very bad. Any help is appreciated. The code below is the defining of the neural network and training of the pytorch model.

            It doesn't work because of lazy evaluation. The call member of model_fit has formula = frmla, unevaluated. The emmeans support for that model is expecting a formula there. It will work if you add a line to the original function:

            This question is a bit confusing so bear with me, it also has to be done with pure Python and no third-party modules.

            I can't seem to assign the correct datatype to the CSV values and assign them to the class attributes.

            I've tried every way I know, looked around for a few days for an answer...

            The value error when FLOAT assigned the "line[4]", and the TypeError if I don't cast the variable.

            I've also tried assigning them to new variables and casting the datatype. I think it is due to the rstrip() and strip() function output.
