Currently I am doing research to chatbot interfaces and make use of eyetracking to test my prototypes.
My eyetracking device creates a csv file with a x and a y coordinate every 16 mili seconds.
I want to plot this information with:
Currently I have the following code:
dataleft = data[c(3,4)]
dataleft_matrix = data.matrix(dataleft)
plot(dataleft_matrix, main="Eyetracking Left Eye", xlab="X-as", ylab="Y-as")`
However, this does not create the axes as I want them to be.
Can someone help me, please?
I'd recommend using ggplot for this, rather than base R. Of course, you may have good reason to prefer plotting using base R, but I find ggplot easier (and faster) to use.
library(ggplot2)
xleft <- c(2,3,4,2,1,2,3,4,5)
yleft <- c(2,3,4,3,2,1,6,5,3)
leftdata <- data.frame(xleft, yleft)
ggplot(data = leftdata) +
geom_point(aes(x = xleft, y = yleft)) +
scale_y_reverse(position = "right") +
scale_x_continuous(position = "top") +
ggtitle("Eyetracking Left Eye") +
xlab("X-as") +
ylab("Y-as")
