#i'm a beginner in rstudio community

#my code is as follows : 

library(seminr)
datas <- read.csv(file = "SURVEY QUESTIONNAIRES.csv", header = TRUE, sep = ",")
head(datas)

simple_mm <- constructs(
  composite("Course Design", multi_items("CD", 1:7), weights = mode_B),

  composite("Digital Literacy", multi_items("DL", 1:5),weights = mode_B),
  composite("Learner's Interaction", multi_items("LI", 1:4), weights = mode_B),
  composite("Learning Satisfaction", multi_items("LS",1:6)))

simple_sm <- relationships(
  paths(from = c("Course Design", "Technology", "Digital Literacy", "Learner's Interaction"),to = "Learning Satisfaction"))

simple_model <- estimate_pls(data = datas,

#error is as follows : 
Error in `[.data.frame`(data, , mm_items) : undefined columns selected

Welcome to R!

First thing is you may want to learn how to ask a programming question in a community.

Here's a quick run through.

FAQ: What's a reproducible example (`reprex`) and how do I create one?

Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it and feel your pain. Then, hopefully, folks can more easily provide a solution. What's in a Reproducible Example? Parts of a reproducible example: background information - Describe what you are trying to do. What have you already done? complete set up - include any library() calls and data to reproduce your issue. data for a reprex: Here's a discussion on setting up data for a reprex make it run - include the minimal code required to reproduce your error on the data…
