Course Notes: Introduction to Data Visualization with ggplot2

# Import any packages you want to use here

# Load the ggplot2 package
#library(ggplot2)

# Explore the mtcars data frame with str()
#str(mtcars)

# Change the command below so that cyl is treated as factor
#ggplot(mtcars, aes(factor(cyl), mpg)) + geom_point()

#el orden para hacer las gráficas es el siguiente: data, astethics, geometries, themes, statistics, coordinates, facets, etc.

#x, y, color, fill, size, alpha, label and shape en el aes

#para asignarle nombre a los ejes  
	#labs(x = "nombre 1",  y = "nombre 2")

 # Set the fill color scale <- para asignarle color a las escalas
  #scale_fill_manual("legend title", values = vectores)

#Modifying aesthetics
	#position
		#Adjustment for overlapping
			#identity
			#dodge
			#stack
			#fill
			#jitter
			#jitterdodge
			#nudge

#ylim() to set the limits on the y-axis
#alpha es para la trasnparencia de colores

#To change stylistic elements of a plot, call theme() and set plot properties to a new value. For example, the following changes the legend position.
	#p + theme(legend.position = new_value)
	#Here, the new value can be
		#"top", "bottom", "left", or "right'": place it at that side of the plot.
		#"none": don't draw it.
		#c(x, y): c(0, 0) means the bottom-left and c(1, 1) means the top-right.

#Many plot elements have multiple properties that can be set. For example, line elements in the plot such as axes and gridlines have a color, a thickness (size), and a line type (solid line, dashed, or dotted). To set the style of a line, you use element_line(). For example, to make the axis lines into red, dashed lines, you would use the following.
		#p + theme(axis.line = element_line(color = "red", linetype = "dashed"))
		#Similarly, element_rect() changes rectangles and element_text() changes text. You can remove a plot element using element_blank()

#To set a single whitespace value, use unit(x, unit), where x is the amount and unit is the unit of measure.

#Borders require you to set 4 positions, so use margin(top, right, bottom, left, unit). To remember the margin order, think TRouBLe.

#The default unit is "pt" (points), which scales well with text. Other options include "cm", "in" (inches) and "lines" (of text).

#theme_gray() is the default.
#theme_bw() is useful when you use transparency.
#theme_classic() is more traditional.
#theme_void() removes everything but the data.
