1 Data conversion

We convert the data from SPPS to R using our convertGUI package.

xguiDF9 <- convertGUI(conf$data_repositories$gui_9_yo, "9-yo-cols.csv", version = 2)
xguiDF13 <- convertGUI(conf$data_repositories$gui_13_yo, "13-yo-cols.csv", version = 2)
xguiDF17 <- convertGUI(conf$data_repositories$gui_17_yo, "17-yo-cols.csv", version = 2)

In wave 1 BMI was not computed directly, computation done here:
