Multiple ifelse statement

Vote count:

I have the below df

      var1 var2 freq1 freq2
1    a    b     5    10
2    b    a    10     5
3    b    d    10    10

created from the following code

help <- data.frame(var1 = c("a", "b", "b"), var2 = c("b", "a", "b"), freq1 = c(5, 10, 10), freq2 = c(10, 5, 10))

my intention is to create an ifelse statement where I am able to (1) replace all freq1 values to 0 when var1 equals a, and (2) replace all freq2 values to 0 when var2 equals a. I do not want to change the value if var1 or var2 is not a.

Is the ifelse command not the best way to solve this problem? I started doing each one manually using help$freq1[help$var1 == "a"] <- 0 however, this will take a bit of time as I have multiple variables and a large dataset. Any assistance would be great.

Many thanks.
