How to Get a Count of a Value in Tidyverse Easily

So hey, listen up! You wanna know how to get a count of a value in Tidyverse? Like, you’re just sitting there all curious and stuff, right? Well you’re in luck cause I’m here to spill the beans. It’s easier than finding your remote control under the couch cushions! Seriously, it is. You might even giggle a bit if you pay attention. So grab your snacks and let’s dive into the wild world of Tidyverse counting!

Step One: Meet Your Data Frame

Okay first things first. You gotta have some data. It’s like going to a party without any snacks – totally pointless!

So imagine you have this magical box called a data frame. It’s just like a big table with rows and columns. But instead of food, it’s filled with numbers and words. So create your data frame with super cool stuff like fruits or animals.

Like this:

fruits <- data.frame(name = c("apple", "banana", "orange", "banana", "apple")) Step Two: Load Up That Tidyverse And now you need to invite Tidyverse to your party. You gotta load it up cause it’s where all the fun tools are at. Just type this shiny line in R: library(tidyverse) Boom! You got the magical powers now. Step Three: Say Hello to Count But wait, here's where it gets real exciting! There’s this function called count(). This little guy is like that friend who always knows how many slices of pizza are left. You can use count() on your data frame like so: fruits %>% count(name)

It’ll tell you how many apples or bananas are hangin’ around.

Step Four: Filtering for Fun

But what if you only wanna see how many bananas there are? I mean, who doesn’t love bananas?

You can filter before you count! It’s like making special orders at restaurants.

Just do this:

fruits %>% filter(name == “banana”) %>% count()

Now you’ll only see the banana squad!

Step Five: Group Up for Extra Fun

And sometimes, counting is more fun when you’re hanging out with friends!

So if you want to be social and group by some category (like color of fruits), you can do that too!

First make sure there’s another column for colors!

Like:

fruits <- data.frame(name=c("apple", "banana", "orange"), color=c("red", "yellow", "orange")) Now try something new: fruits %>% group_by(color) %>% count()

Look at that! You’re counting colors like a pro!

Step Six: Mix It Up with Summarize

Okay now we’re getting fancy!

You can mix summarize() with count() for even more fun results!

Let’s say we wanna know how many apples and oranges together there are. Just do this:

fruits %>% filter(name %in% c(“apple”,”orange”)) %>% summarize(total = n())

Suddenly you’re both counting AND summarizing. Sounds fancy huh?

Step Seven: Plotting Your Counts

But wait—there’s one last super cool thing to do!

You can visualize those counts! Like making art but with numbers!!

After you count your values, throw them into ggplot2 like so:

fruits %>% count(name) %>%
ggplot(aes(x=name,y=n)) + geom_bar(stat=”identity”)

Ding ding ding!!! Now people will be impressed by your counting skills and art skills at the same time.
