Hi,
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

If you read the data into a data frame, you should be able to simply pass the name of
the data frame in a call to boxplot.
my.data - read.delim(mytext.txt)
boxplot(my.data)
If you only want a boxplot of column 5
boxplot(my.data[,5])
See ?boxplot for other options to make the boxplot look the
Have you considered normal probability plots (qqnorm) to identify
outliers? These will identify much more, of course, including the need
for transformations, mixtures of distributions, etc.
