Plotting values of the same column grouped by an ID

Question

I am working with R.

I have a tibble that have many columns, including these two...

Condition  Strength 
  A           0.05
  A           0.3
  A           0.2
  A           0.6
  A           0.2
  B           0.8
  B           0.4
  B           0.7
  B           0.9

I am trying to plot the data like this (then I will add a few more things)...

ggplot(mydata, aes(x = filter(condition == "A" %>% select(Strength)), 
                   y = filter(condition == "B" %>% select(Strength)))) +
  geom_point()

This gives me nothing.

So, what I want is to treat the strength as two different vectors dividing them considering the condition.

Answer 1

Perhaps you want a boxplot?

ggplot(mydata, aes(x = Condition, y = Strength, fill = Condition)) +
  geom_boxplot(show.legend = FALSE)
