Plot All Columns of Data Frame in R (3 Examples) | Base R vs. ggplot2 | How to Draw Each Variable

R code of this video:

y1 = rnorm(10),
y2 = runif(10),
y3 = rpois(10, 1))

plot(data$x, data$y1, type = "l", col = 1, ylim = c(- 3, 3)) # Plot with Base R
lines(data$x, data$y2, type = "l", col = 2)
lines(data$x, data$y3, type = "l", col = 3)

y = c(data$y1, data$y2, data$y3),
group = c(rep("y1", nrow(data)),
rep("y2", nrow(data)),
rep("y3", nrow(data))))

library("ggplot2")

ggp ＜- ggplot(data_ggp, aes(x, y, col = group)) + # Create ggplot2 plot
geom_line()
ggp # Draw plot

ggp + facet_grid(group ~ .) # Draw plot in different panels

I was figuring out it for 2 hours and you explained it in 6 minutes.
Thx dude!

many thanks for what you are doing
your videos and website are of great help

when reshaping the data frame, it returns me an error: Error:
! Tibble columns must have compatible sizes.
• Size 97: Existing data.
• Size 485: Column `y`.
ℹ Only values of size one are recycled., how can I resolve this?

Help, please! line graph does not appear for my data. This appeared on my console "geom_line()`: Each group consists of only one observation.
ℹ Do you need to adjust the group aesthetic?"

Thanks for the nice video! I have problems to use it with different series lengths. It is possible to draw different time series (with different length) in seperated plots in one window with ggplot? :)
