Why? No always los of RA opporuniies in our laboraory from semeser o semeser. Provide opporuniy for awesome sudens who applied or from recen classes o gain some experiences. To ranslae some cogniive science ino day-oday pracice, hone raining maerials, disseminae resources, ec. Caveas Goals This workshop will be a rough draf. Maerial may no always be super clear, however I will be here o collaborae on RSudio. Learn some solid RSudio. Learn how o plo and describe daa ha is organized in ime. Apply his knowledge o real-world case sudies. Today: we sar slow and simple jus o ge everyone on he same page.
