Flat complex numbers in R with ggplot2

Question

Is there a way to build a complex number in an elegant way using ggplot2 ? plot {graphics} does this for my snowflake vector of values, but I would rather have it in ggplot2 . The ggplot2 I came across do not mention the compound word.

 snowflake <- c(complex(real=0, imaginary=0), complex(real=1/3, imaginary=0), complex(real=1/2, imaginary=(3^(1/2))/6), complex(real=2/3, imaginary=0), complex(real=1, imaginary=0)) plot(snowflake, type="l") 

UPDATE

Unfortunately, it seems that the following proposal is not working with my more complex figures - plot {graphics} builds points in the order specified by the values of the vector, whereas qplot not. Example:

 my.snowflake <- c( 0.0000000+0.0000000i, 0.1111111+0.0000000i, 0.1666667+0.0962250i, 0.2222222+0.0000000i, 0.3333333+0.0000000i, 0.3888889+0.0962250i, 0.3333333+0.1924501i, 0.4444444+0.1924501i, 0.5000000+0.2886751i, 0.5555556+0.1924501i, 0.6666667+0.1924501i, 0.6111111+0.0962250i, 0.6666667+0.0000000i, 0.7777778+0.0000000i, 0.8333333+0.0962250i, 0.8888889+0.0000000i, 1.0000000+0.0000000i) 

Results:

 plot(my.snowflake, type = "l") 

 qplot(Re(my.snowflake), Im(my.snowflake), geom="line") 

Answer 1

Just extract the real and imaginary parts of the number with Re and Im , and then pass them to ggplot2 as x and y:

 qplot(Re(snowflake), Im(snowflake), geom="path") 

In your update, you indicated that geom_line does not work for a non-trivial case, so instead you want to use geom_path , which connects the points in the order in which they are provided. Here is your more complex geom_path example:
