Hello,
I want call my function (use my database) and write every result in matrix
"wynik" but I always get an error: Error in wynik[, i] <- dodawanie(wzorzec,
wzorzec1) :
number of items to replace is not a multiple of replacement length
I'll be very happy if sb help me
dodawanie<- function ( wzorzec, wzorzec1){
wynik1<-wzorzec + wzorzec1
wynik2<-wzorzec * wzorzec1
wynik <- c(wynik1,wynik2)
return (wynik)
}
df=data.frame(a=c(1,2,3),b=c(9,9,9),c=c(4,3,2)) # This is my database ;)
wynik=matrix(0,nrow=10,ncol=2)
# and my loop
for(i in 1:ncol(df)){
procent_graniczny <- 10
wzorzec=df[,i]
wzorzec1=ifelse(df$a==3,1,ifelse(df$c==4,2,3))
wynik[,i] <- dodawanie ( wzorzec, wzorzec1) # <- Here is my problem
!!! I want in "wynik" have got result from my function (one by one)
}
