QUESTION
Following is my implementation of the algorithm to find the LPS array which is part of the KMP algorithm.
...ANSWER
Answered 2021-Jun-01 at 19:33What is j? This is length of current prefix.
At every step we make suffix longer by one, and we may get coinciding prefix longer by one. But prefix length might become smaller, and sometimes zero. But if we make prefix of zero length, and will expand it one char-by-one, we have to perform a lot of operations. Instead this algorithm uses smart optimization - prefix length is diminished by one to reuse already calculated information.
The most important moment - overall number of prefix reductions cannot exceed string length - that is why complexity is linear.
QUESTION
Im using nodejs/express view engine in my application. This means that when the route points to an existent url, an assigned template would be rendered onto the screen. I have previously implemented a redirect to the homepage whenever a user types in an unexisting url. However, now, I have an wordpress endpoint which is to/stores and I am trying to do a redirect to that instead of a previous template that I had. The issue is that when I click on the href link, it goes straight to homepage, because this time it is not a template, but a route. So it doesnt fit into the 'view engine' type of view. Please see my code below for what I mean. Thanks!
Here in app.js, I am doing the redirecting to the homepage if there is an nonexisting route that:
...ANSWER
Answered 2021-May-01 at 05:12It seems that your application doesn't define "/to/stores" route, so user is first redirected to that route and then the catch all middleware redirects the user to homepage.
If you want to redirect user to different application, you need to use the absolute url of that application. i.e. res.status(301).redirect("https://example.com/to/stores")
If instead you want to handle "/to/stores" route in this application you need to add /to/stores route handler to your app, i.e.

QUESTION
[
I am trying to develop a shiny app and I am using a slider input to control the colour parameter defined in geom_point() using a series of conditional ifelse statements according to the code below.
The code is working, however the colours are not consistent when the legend goes from 3 colours to 2 colours. For example, "Down" is Green, "Unchanged" is Grey and "Up" is Red. As I vary the input$FC, the legend changes to 2 colours and now, Unchanged is Green and UP is grey. I would like to maintain the colour coding consistent regardless of how many colour are shown in the legend. Here's my code for ui and server: library(shiny)
...ANSWER
Answered 2020-Nov-11 at 04:13When you specify colors with scale_*_manual(values=...), the colors are assigned to the aesthetic variable in your dataset according to the ordering of the levels of that particular factor. You're assigning values "on the fly", so to speak, with the ifelse() part of the code, but the general rule still applies here. After the values of "Down", "Up" or "unchanged" are assigned, the levels for that factor are used to associate with your colors indicated. If not otherwise specified, the ordering of the levels would default to alphabetical, which is why the order appears "Down", "Unchanged", and "Up" (although that can be changed in your legend if you wish...).
The easy solution here is to know that you can pass a named vector to scale_*_manual() instead of just a vector of colors. This will define the colors associated with specific level names, regardless of whether they exist in the final plot. In other words, the following should work in all cases:
QUESTION
I have a PCA plot that ive been working on a while now (I am not very good at R but this is teaching me a lot, just trying to make this one plot). I am now at the stage where the plot looks how we want it, now we just want to draw ellipses around the replicates. (see plot below)
Ideally, the ellipses would have the border colour the exact same colour and be filled in with a mostly transparent version of that same colour (see example plot below)
Many people have suggested using ggbiplot, which i tried but i found the manual very sparse in detail and i didnt really understand how to control the plot. To generate the plot i used the following code:

QUESTION
I am trying to create several PCA plots for different experiments. For each plot, i want the same colour point for each variable. So in my ggplot, i use scale_colour_manual and assign a list of colours in the order of the samples, however, these seem to randomly assign to each variable (grey is first colour listed and should map to cells as this is the first variable, but it doesnt.
