Make a set of R lines based on the following guidelines. ( each one has 4 points) 1. Make some simple data vectors (numerical or text) using the c () command. 2. Use the scan() command to enter numerical data; this is quicker as the items can be separated by simple spaces (spaces are the default, but other separators can be used). 3. Use the scan0) command to enter some text; this requires extra instruction, what = "character". Items only require separation with a space and do not need to be enclosed in quotes. 4. Text items are dealt with similarly to step 3: you use the what = "character" instruction. 5. Now show how to use the scan() command to read a simple text file. 6. This is a convenient time to show how to alter the working directory using the setwd) command. The dir() command can also be demonstrated. 7. Now show how to read larger and potentially more complex data from disk using the read.csv0 command. 8. Use files in various formats (comma delimited, tab, space) to give your class some practice at using the read.csv0 command and the variants such as read.table0
