I am a beginner user of R. I have a trivial question I am almost
ashamed I cannot figure it out does not matter how many times I
am reading the help.
I have a table in .txt format, tab delimited. I can read it with
read.delim() with no problems.
Afterwards I would like to use boxplot function to see if there
are any outliers in the column 5 of my data called TPAH16.ppm
In the boxplot help I saw that I have to declare my data with
data(). I am getting errors does not matter how I am calling
data(), only with the name of the table, with
data(read.delim()), or in any other way. So in the end I was not
able to use boxplot at all.
I will appreciate any help for dummies you can give me. Also,
if you know any other way to identify outliers, or to use Cook
dimension to identify them, I will really appreciate.
