Trying to filter my data

[Carootje]

Hello,
Im really struggling with my R at the moment. I have a dataset with some amount of questions, and Im investigating the extreme answers given. In a 1-5 scale, thats 1 and 5. For that I wrote a code (Question 1 is called Q1S5):

dat[dat$Condition =='1'$Q1S5 == 1 | dat$Q1S5== 5,]$Extreme1S5 = 1
dat[dat$Condition =='1'$Q1S5 == 2 | dat$Q1S5== 3 | dat$Q1S5== 4,]$Extreme1S5 = 0

Now I want to filter using my column 'Condition' which has value 1 or 2, depending on the condition. I want to investigate condition 1.

I wrote this: dat[dat$Condition=='1',]$Q1S5 == 1 | dat$Q1S5== 5,]$Extreme1S5 = 1

But it doesn't work. I don't know how to do it, can anybody help me?

Is there a possibility to make a new dataset filtering on Condition 1?

It is not really clear to me what you are doing here. Could you provide FAQ: How to do a minimal reproducible example ( reprex ) for beginners and 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.
