It's not a data.frame. You can use str() to look at the *str*ucture
of an object:

Ggplot2 also depends on factors, so learn about them asap. It does have some
support for automatically converting strings to factors in some cases, but it
doesn't always work the way you want it to.

Hello William, Ivan and Jim
I appreciate your replies.
I did suppress the factors using stringsAsFactors=FALSE and in that way
was able to progress some more on getting a sense of the data set, so
thanks for that suggestion. I had previously overlooked it.
Also thanks William, I never understo
Here is a reproducible example

'data.frame': 3 obs. of 2 variables:
$ Name: Factor w/ 3 levels "Adam","Bob","Xavier": 2 3 1
$ Age : int 2 25 1
Do you get something similar? If not, show us what you have (you

If you are using 'read.csv' (or 'read.table') to input, then use the 'as.is
= TRUE' parameter to prevent the conversion to factors of the data.
You can also do "as.character(df$col_with_factors)" to get the character
values back.

Hi Sun,
If I understood correctly (a reproducible example would be of great
help), it seems you're struggling with factors. Read on this topic to
better understand how it works.
For your plots, you would need to set the labels with the argument
'xlab' for plot(). To access the names of the f
