R question

I am trying to create this function, but I think the problem parts are where I tried to put macro tokens (e.g., var1, var2, var3) within "".    I'm getting error messages.  Any suggestions welcome.  Rでファンクションを書いているのですが、” ”の間に、var1,var2,var3を入れるとエラーが出ます。どうしたらいいでしょうか? This is the error message:

Error in eval(cols[[col]], .data, parent.frame()) : 

object 'var3.y' not found




analysis_data %>%
mutate(difference=var3.y-var3.x) -> analysis_data_b
analysis_data_c<-filter(analysis_data_b,difference >= 0)

result01pre <-Summarize(var3.x ~ group.x, data= analysis_data_c)
result01pre$surveyID<- "var2"
result01pre$tableID<- "var1"
result01pre$item<- "var3.x"
result01pre=subset(result01pre,select=c(tableID, surveyID, item,test_type,group.x,n,mean))

result01post<-Summarize(var3.y ~ group.y, data= analysis_data_c)
result01post$item<- "var3.y"

result01diff<-Summarize(difference ~ group.x, data= analysis_data_c)
result01diff$item<- "difference"

all01<-merge(all01,result01diff,by.x="group.x",by.y="group.x",all.x = TRUE, all.y = TRUE)
#Paired t-test algorithm

all01 %>%
