so im trying to implement a search box with useState and useEffect. we have an array of objects and want to filter it according to our search term. here is my implementation:

I have a tibble (data.frame) that I need to apply a number of type updates to. I have a readr::col_spec object that describes the desired types, but since the data does not originate as a csv file, I cannot use read_csv(..., col_types=cspec) to apply the changes to the specified columns.

Since col_spec is a data structure designed exactly to specify desired data types, I would nevertheless to use it directly as an input to a function that applies the changes for me, rather than writing a long custom script to apply the different columns. See the following example:

I'm new to React and having some trouble displaying the data I want. I'm building a very basic search and filter app and I'm stuck. All of the data is coming from App.js

I can search by "name" just fine. I'm having trouble filtering by "name", "dob" and "gender".

How do I do that correctly with the code I have?

App.js

I have a table called 'names':

Using the starwars dataset, below is a minimal example of the issue I am facing.

My app has three selectInput for filtering out a datatable. These selectInput update each other depending on the selected value of the previous one.

The app also contains radio buttons for selecting type characters. When the radio button 'default' is clicked, the selectInput should select the first value among the choices by default. However, when a radio button is a character (i.e. not 'default'), the selectInput should update and select the value defining the character (through a reactive object info()). As a consequence of the change in selection of the selectInput, the table should be filtered accordingly.

(The only constraint I have to follow here, is that I cannot use the dataset in the UI of the app.)

Here is the example app.

I'm trying to use SimpleTransformers default setup to do multi-task learning.

I am using the example from their website here

The code looks like below:

I'm trying to reproduce the following output of dplyr code with R package collapse.

dplyr Code

I have an HTML string where I'm trying to generate an array of all substring instances that occur between two sets of characters.

My string looks something like this:

I'm stucked, lost... I'm using gatsby-plugin-algolia, when I search, the empty fields are filtered. They are generated by the PostPreview component.
