Hi Joe,
What about this? Btw, the real key to a reproducible example is one
that we can actually work with----output of the summary of the data is
not the same as the data itself. That makes it tricky to know what
exactly you are working with (although sometimes the original form of
the data can be intuited from the summary output). For future
reference, providing the output of something like:
dput(head(Names))
would make it easier for us to read your data in, and then we have
exactly what you are working with and can offer advice more easily.
## Read data in
Names <- read.table(textConnection("
V1 V2
1 First001 Last001
2 First002 Last001
3 First003 Last002
4 First004 Last003"), header = TRUE)
closeAllConnections()
# barplots of table()d results
barplot(table(Names$V2))
barplot(table(Names$V2))
Cheers!
Josh

I thought I did, but I'll restate it again I have data imported from a file with first and last names
Names <- read.table("Name.txt", header = FALSE)
Names
? ? ? ? ? ? ? V1 ? ? ? ? ? ?V2 1 ?First001 ?Last001 2 ?First002 ?Last001 3 ?First003 ?Last002 4 ?First004 ?Last003 I can produce a summary of the Names data
Summary(Names)
? ? ? ? ? ?V1 ? ? ? ? ? ? ? ? V2 ?First001: 3 ? Last001: 9 ?First002: 3 ? Last002: 7 ?First003: 3 ? Last003: 7 (Other): 52 ? ?(Other): 27 This summary result contains the quantity of First001 entries ? I want this put into a vector along with the quantity so I can actually plot it. the command you gave will not work
hist(Names$V1)
Error in hist.default(H02) : 'x' must be numeric You could try
hist(table(Names$V1))
but it produces the wrong plot table(Names$V1) is the right stuff but the plot produced by hist(Names) is not correct
hist(Names$V1, plot = FALSE)
it produces $breaks [1] 1.0 1.5 2.0 2.5 3.0 $counts [1] 34 11 ?0 ?4 $intensities [1] 1.3877551 0.4489796 0.0000000 0.1632653 $density [1] 1.3877551 0.4489796 0.0000000 0.1632653 $mids [1] 1.25 1.75 2.25 2.75 $xname [1] "pathways" $equidist [1] TRUE attr(,"class") [1] "histogram" Which is all wrong!!!!
