Hi guys, I am kindly asking if you can help me with this issue. When I try to divide trials based on some conditions I get this message "Error in $<-.data.frame(*tmp*, foiltype_level, value = numeric(0)) : replacement has 0 rows, data has 4248"
Here are the codes I have used:
#FOIL 0: Completely Different
df_raw$target_cat[df_raw$pictureList =="Training/Slide1.jpg" | df_raw$pictureList =="Training/Slide4.jpg"| df_raw$pictureList =="Training/Slide7.jpg"| df_raw$pictureList =="Training/Slide10.jpg"| df_raw$pictureList =="Training/Slide13.jpg"| df_raw$pictureList =="Training/Slide16.jpg"| df_raw$pictureList =="Training/Slide19.jpg"| df_raw$pictureList =="Training/Slide20.jpg"| df_raw$pictureList =="Training/Slide21.jpg"| df_raw$pictureList =="Training/Slide24.jpg"| df_raw$pictureList =="Training/Slide25.jpg"| df_raw$pictureList =="Training/Slide26.jpg"| df_raw$pictureList =="Training/Slide37.jpg"| df_raw$pictureList =="Training/Slide40.jpg"| df_raw$pictureList =="Training/Slide43.jpg"| df_raw$pictureList =="Training/Slide46.jpg"| df_raw$pictureList =="Training/Slide49.jpg"| df_raw$pictureList =="Training/Slide52.jpg"| df_raw$pictureList =="Training/Slide55.jpg"| df_raw$pictureList =="Training/Slide56.jpg"| df_raw$pictureList =="Training/Slide57.jpg"| df_raw$pictureList =="Training/Slide59.jpg"| df_raw$pictureList =="Training/Slide60.jpg"| df_raw$pictureList =="Training/Slide61.jpg"]<- "Foil0"

df_raw$foiltype_level[df_raw$foiltype == "Foil0"] <- 0 # Foil Type 1:
df_raw$foiltype_level[df_raw$foiltype == "Foil1"] <- 1 # Foil Type 2:
df_raw$foiltype_level[df_raw$foiltype == "Foil2"] <- 2 # Foil Type 3:
Your help is very appreciated!
