Really enjoying these videos, Julia. Please keep 'em coming. I'm planning a quantitative corpus-based study of the use of metaphors in classical music reviews, and I'm considering how I should approach it. This is a new area for me.
Would it not make sense to use REGEX one-liners to generalise a lot of the replacements? match = "(orange|grapefruit|lemon|...)\s?juice", replace = "$1" match = " ?([0-9])/([0-9])", replace = "$1 $2" %>% str_split(" ") %>% function(x) {x[1]/x[2]}
Hi Julia, I am working on a project and am stuck between two general types of errors when prepping my PCA recipe: the first is this: Error in svd(x, nu = 0, nv = k) : infinite or missing values in 'x' I interpret this to be some issue with missing data so I have tried both step_naomit and step_other as solutions. When I go to prep these updated recipes, I get errors along the lines of: ℹ It must be numeric or character. Backtrace: 1. recipes::prep(pca_rec, training = datatest) 26. rlang::cnd_signal(``) Do you know what might be going wrong? Thanks!
Hmmmm, it's hard to say from just this information. I suggest that you create a reprex demonstrating your problem: www.tidyverse.org/help/ And post on RStudio Community: rstd.io/tidymodels-community That is a good place to get help for R coding problems. Good luck!
Im a beginnerish and boy do I wish I had found your videos earlyer. I bow in signal of respect.
Thank you again Julia. Bravo on the speed and advance topics covered.

Amazing Julia! You make PCA & UMAP concepts crystal clear!
Great stuff!! Watching your programming fluency (specially in the ggplot2 part) was absolutely amazing! Thanks for posting the video!

Thanks Julia, that was amazing!
Bravo, bravo, bravo
I am supposed to write my final papers but instead, I am trying to learn from you.
Awesome stuff, I love your style in presenting the topic, and has really helped with tidymodels and PCA. Many Thanks
Amazing! Great stuff. Thank you.
Love your videos, thank you. Hope to see at some point PCA that does NOT use recipes.
If you don't want to use tidymodels for PCA, you might like Claus Wilke's approach here:

@@JuliaSilge thank you!!!
Julia you are amazing! :)
Your videos are therapeutic haha
Wow, umap is already in r !
just moved to umap over tsne.
Julia you are a goddess!! Thank you.
Great tutorial, thank you
Great presentation! Dashboard issues. Power BI and umap are not dancing together.
i love your videos
Would it not make sense to use REGEX one-liners to generalise a lot of the replacements?
match = "(orange|grapefruit|lemon|...)\s?juice", replace = "$1"
match = " ?([0-9])/([0-9])", replace = "$1 $2" %>% str_split(" ") %>% function(x) {x[1]/x[2]}
Yes, I think I even said that at 6:54 or so, that it would have been better to use a little function.
Thanks Julia! :-)
Thanks Julia! Can you ggplot a rotating 3D plot with the first 3 components?
You might check out the tourr package for something like that: ggobi.github.io/tourr/
Great Presentation. However I would have liked a little more explanation on the UMAP, But otherwise 9.5/10.
Julia - considered putting all this code on github? Would make it a lot easier to reference! Thank you.
You can find the code that builds my blog here: github.com/juliasilge/juliasilge.com

Love your work Julia, but could you please ask TH-cam to stop subtitling you as Julia Silly as you clearly are not 😂
HA I really should work on doing my own subtitles instead of letting TH-cam autogenerate them!!
