QUESTION
I'm trying to create a plot that contains both a violin plot and a stripplot with jitter. How do I go about doing this? I provided my attempt below. The problem that I have been encountering is that the violin plot seems to be invisible in the plots.
...ANSWER
Answered 2022-Apr-17 at 13:51As you suspected, the different scales will make the violin very small in the stripplot unless you adjust for it. In your case, you have also accidentally capitalized Density:Q
in the channel encoding, which means that your violinplot is actually empty since this channel doesn't exist. This example works:
QUESTION
I'm having trouble with the facet.by parameter of the ggerrorplot fonction. When I use a grouping variable, the facets still show all data labels in both groups, but with blank spaces. Is there a way to erase the extra labels, or to recreate this in ggplot? thanks!
...ANSWER
Answered 2022-Apr-16 at 12:02Haven't found an option in the docs but you could free the scales by manually adding a facet_wrap
.
Using the default example from ggpubr::ggerrorplot

QUESTION
I have an issue with jittery movement and I have searched the internet thin and tried countless solutions, but none have worked.
Essentially, I am moving a 2D Enemy GameObject towards my player, which involves moving and rotating at the same time.
At the start it is smooth, but when my player shoots the Enemy, causing it to fly backwards because of the RigidBody2D physics, it starts jittering when it rotates back towards my player.
Also, when my enemy tries to rotate back towards my player after getting hit, it struggles to aim/rotate directly at my player. It's just kind of struggling to rotate the last 20 degrees while jittering.
I have tried EVERY combination of using velocity and AddForce for movement, and using FromToRotation, RotateTowards, Lerp, and Slerp for rotation.
I have tried using both Update, LateUpdate, and FixedUpdate for either or both moving and rotating.
I have tried setting the GameObjects Interpolation to None, Interpolate and Extrapolate.
Nothing works.
My best guess is that my RotateEnemy() somehow gets confused about what "forward" is after getting hit, and doesn't know what to point at the player.
Here is a video showing the issue:

Here is the script I have on my Enemy gameobject:
...ANSWER
Answered 2022-Apr-11 at 11:13Based on your reply I would suggest you to call your RotateEnemy()
in Update
.
Update
runs on every frame, where FixedUpdate
does not - it runs per physics tick, and more or less than one of those may occur each frame.
And since we are not handling physics related stuff in RotateEnemy()
we should call it in Update()
QUESTION
I'm using this nice boxplot graph, answer from @Parfait.
- I got an out of bound error on
j
and had to userange(i*5,i*5+5)
. Why? - I'd like to set the median to a particular color, let's say
red
.medianprops=dict(color="red")
won't work. How to do it? - How to set the y-axis tick labels to the same color as the boxes?
Disclaimer: I don't know what I'm doing.

QUESTION
not very big on JS. I currently have a script I use to load/change background images every xxx seconds.
What I would like is to display an image and preload the next one so it displays seamlessly (ie: no jittering or slow loads).
Here is my current script, can this be adapted to achieve such a result?
...ANSWER
Answered 2022-Mar-28 at 13:40You could just load the next image when displaying the current one using the JavaScript Image
object. When switchImages
runs again then the image will be already in the browsers cache. Also, the cached images are stored in a new array, so the cache "generator" will be ran only once. With this snippet you will need enough delay between iterations, so the next image will have enough time to be downloaded from the sever.
QUESTION
The question I have has mostly been answered by the following post: Cannot update/edit ggplot2 object exported from a package (`gratia`) in R. When I refer to the mydraw.gam function, it comes from code in that post. What I am trying to do is use the mydraw.gam function with a rugplot that looks like the gratia::draw() function.
This is my data:
...ANSWER
Answered 2021-Dec-03 at 10:17I would just use smooth_estimates()
and its draw()
method to plot a single smooth from the model. You can then add to it using standard ggplot2 functionality...
QUESTION
I'm trying to include a black box likelihood function in a pymc3 model. This likelihood function just takes a vector of parameter values and returns the likelihood (all data is already included in the function).
So far I've been following this guide and have modified the code as follows to accommodate the fact my model only has one parameter k.
...ANSWER
Answered 2021-Nov-05 at 09:42As per the comments I checked out this thread and discovered that pm.potential really was the cleanest way to achieve black-box likelihood. Modifying the code above as follows did the trick:
QUESTION
One of the variables in my data frame is a factor denoting whether an amount was gained or spent. Every event has a "gain" value; there may or may not be a corresponding "spend" amount. Here is an image with the observations overplotted:
Adding some random jitter helps visually, however, the "spend" amounts are divorced from their corresponding gain events:
I'd like to see the blue circles "bullseyed" in their gain circles (where the "id" are equal), and jittered as a pair. Here are some sample data (three days) and code:
...ANSWER
Answered 2021-Sep-23 at 15:19My main idea is the old "add jitter manually" approach. I'm wondering if a nicer approach could be something like plotting little pie charts as points a la package scatterpie.
In this case you could add a random number for the amount of jitter to each ID so points within groups will be moved the same amount. This takes doing work outside of ggplot2.
First, draw the "jitter" to add for each ID. Since a categorical axis is 1 unit wide, I choose numbers between -.3 and .3. I use dplyr for this work and set the seed so you will get the same results.
QUESTION
I want to plot the regression between a response variable and one of the explanatory variables in a mixed effects model while also showing the data points. For this I am using the function plot_model()
. I would also like the data points to have different colours or shapes according to the random effect. I do not want to plot the different regression lines for each level of the random effect. Is this possible with plot_model
?
This is the data:
...ANSWER
Answered 2021-Sep-01 at 15:20If you set show.data = FALSE
in your plot_model()
call and then add the points separately it seems to work OK:
QUESTION
C++20 concepts adds an alternative way to access iterator traits. For example iter_value_t
gives a similar result as iterator_traits::value_type
.I have noticed that
iterator_traits
do not appear to work in concept constraints.iter_value_t
works for concepts, but it also works everywhere else.
So my hunch is I should use the newer iter_value_t
since it works in both contexts.
Is this correct? When should I prefer one or the other?
EDIT: I was missing typename
when using iterator_traits in concept constraints. The concepts gave me the jitters!
ANSWER
Answered 2021-Aug-21 at 21:25iter_value_t
is used to implement algorithms in terms of indirectly readable types. iterator_traits
is used to implement algorithms in terms of iterators.
Indirectly readable types are types that can be read by applying operator*
. That includes pointers, smart pointers and iterators. All such types satisfy indirectly_readable
concept.
To fully understand the idea behind the iter_value_t
we need to take a look at it's implementation.
If std::iterator_traits>
is not specialized, then std::iter_value_t
is std::indirectly_readable_traits>::value_type
. Otherwise, it is std::iterator_traits>::value_type
.
You can see that if it is possible it tries to default to iterator_traits but additionally applies remove_cvref_t
transformation to the types. This allows it to work with const-volatile-reference qualified types such as const char* const
or const char*&
etc.
Is this correct?
No, iterator_traits
work with concepts as well (unless I misunderstood what you've meant by that).
