Hi! I am new to R and I've run into problems when trying to run a t test on my data. I am trying to determine if there is significance between my independent and dependent variable under these conditions, I inputted this:
library(tidyverse)
attach(D_D_Sacc_Bottle_Data_stats_in)
select(PCB Treatment, Average .75%)%>%
filter(PCB Treatment == "A" | PCB Treatment == "B") %>%
t.test(data = df, Average .75%~PCB Treatment)
and was met with this error:
Error in UseMethod("select_") :
no applicable method for 'select_' applied to an object of class "character"
What does this mean and how do I fix it?
Thank you!
