Dear R users;
I am MSc student and I want to write my own function, but it cant be
completed. please help me for solve it. here is my code:
pah1$P = (pah1$Fluoranthene/pah1$Pyrene)
T = function(x){
for (i in 1:length(pah1$P))
if (i >= 1)
print("Combustion")
if (i < 1)
print("Petroleum")
}
T(pah1$P[c(1:83),])
I wish that R gives me a column that if value greater or equal to one give
"Combustion" and if value is less than one give "Petroleum".
but my function dose not work.
thank you so much for your help.
