Vectorized IF statement combined with logic AND in R

Question

This is my code I wish to have:

a=1
b=c(2,1.5,0.7)

if (a==1 & b<1) {

     b=1   # but here's the problem, that only the first value of the vector b is considered

}  # end if loop

print(b)

Okay, I could also write this code like this but I hope I can prevent it with your help.

a=1
b=c(2,1.5,0.7)

if (a==1) {

     for (i in 1:length(b)) {

          if (b[i]<1) {

               b[i]=1  

          }  # end if loop

     }  # end for loop 

}  # end if loop

print(b)

I also have found this question Vectorized IF statement in R? but I cannot transfer it to my issue...

Thanks for your help in advance.

Is this what you are looking for `as.integer(a == 1 & b < 1)`? — tmfmnk, Mar 17 '20 at 07:19
BTW `if` is not a loop. Correct you could write `# end of the then-block` — jogo, Mar 17 '20 at 07:34
@tmfmnk: when I put this in my if-statement, the condition has length greater than 1 but only the first element of the vector b is used. So the problem remains - I hope I interpreted your comment right. — tueftla, Mar 17 '20 at 07:55

b <- ifelse(a==1 & b<1, 1, b)
