Me da error este ejercicio y no sé si se puede hacer de otra forma

Añadimos una columna 'aprobado' a dat1

dat1$aprobado <- 0

Analizamos las filas de dat1

for(i in 1:nrow(dat1)) {

Si la nota del alumno es mayor o igual a 5, cambiamos el valor de 'aprobado' a 1

if(dat1$notas[i] >= 5){
dat1$aprobado[i] <- 1
}
}

Mostramos las primeras filas de dat1 para comprobar el resultado

head(dat1)

I think we need to see some sample data.
A handy way to supply some sample data is the dput() function. In the case of a large dataset something like dput(head(mydata, 100)) should supply the data we need. Just do dput(mydata) where mydata is your data. Copy the output and paste it here between
```

```

Here is an example of the code working. Does this code work for you?

dat1 <- data.frame(notas = c(8,6,9,10,3,7,4))
#Añadimos una columna 'aprobado' a dat1
dat1$aprobado <- 0
#Analizamos las filas de dat1

for(i in 1:nrow(dat1)) {
  #Si la nota del alumno es mayor o igual a 5, cambiamos el valor de 'aprobado' a 1
  
  if(dat1$notas[i] >= 5){
    dat1$aprobado[i] <- 1
  }
}
#Mostramos las primeras filas de dat1 para comprobar el resultado

head(dat1)
#>   notas aprobado
#> 1     8        1
#> 2     6        1
#> 3     9        1
#> 4    10        1
#> 5     3        0
#> 6     7        1
