Just a small test to plot the data exported by the tobii eyetracker in R
- Go to r-project.org/
- download and install R for your OS from one of the servers
##Mac OSX
Open a Terminal window and enter the follwing code (This creates an R envoirment file in your home directory)
echo "R_LIBS=/Users/$HOME/rLibrary" > $HOME/.Renviron
Creates a folder called "rLibrary" in your homefolder. All installed libraries will go there. Type:
mkdir ~/rLibrary
###Start R.app from your Applications folder
in the R console. Check your current working directory by entering:
getwd()
The result should point to your home folder.
####Set your working directory to somewhere where you can remember. e.g the Desktop or whereever you cloned this repo.
setwd("/Users/[YOUR USER NAME]/Desktop/tobii-Eyetracker-R")
Now you can place files in there and read them with R.
Open the eyetracker.R with the R.app.
Select the lines you want to execute
select:
data <- read.table("tobii-CSVExport-All-Data-noheader-nofilter.tsv",sep="\t", header=TRUE)
# plot(data$GazePointX,data$GazePointY, main="eyetracker", sub="",xlab="X-axis GazePointX", ylab="GazePointY", ylim=c(1024,0), xlim=c(0,1280))
# png(filename="out.png", width = 1280, height = 1024,)
par(bg = 'black')
plot(data$GazePointX,data$GazePointY, sub="", xlab="", ylab="",axes=FALSE, ylim=c(1024,0), xlim=c(0,1280),col="black")
points(data$GazePointX,data$GazePointY, col = "green", cex = .6)
lines(data$GazePointX,data$GazePointY, col = "white")
hit cmd + enter. This should open a window with your plot that looks like this:
