Re: [R] Plotting graph problem!!
Yea,i am very new to R. Thanks a lot Jim Lemon! I appreciate it very much!! Hi Andrew, As you seem to be an R newbie and some of the replies may have been cryptic to a newbie, try this: boxplot(a$Life.Expectancies.at.Birth) To explain the above a little bit, when reading in a text file, R does some silent substitutions, like sticking full stops (.) in where there were spaces in the field labels. The dollar sign operator means "return the list element of "a" - a data frame column in this case - that has the name after the dollar sign. That gives the "boxplot" function a vector of numeric values and it knows what to do. These things are so familiar to most of us that we don't bother to explain them. You will probably encounter more of these little mysteries as you progress with R. Good luck.

Should be hist(a$Life.Expectancies.at.Birth), of course. Sorry.

Re: [R] Plotting graph problem!!
I assigned the dataset to data1,then i tried typing hist(data1),it says:
Error in hist.default(data1) : 'x' must be numeric
how can I change the Locations to frequency so that it is in numeric form
and I can plot the histogram?
You should probably tell us which part of
a<-
read.csv("http://r.789695.n4.nabble.com/file/n3389613/Life_Expectancies_2008.csv";)
hist(a)
doesn't do what you expect.
(Though often when people say "histogram" they want something else -
what's with that anyhow?)

so this thing showed up:

I am trying to plot a histogram base on the file i uploaded above. I am
facing a trouble in sorting out the frequency of the life
expectancies. I
wanted to plot a graph of life expectancies at birth versus
frequency,but i
have no idea how to change the locations into frequencies taking the
range
of life expectancies at birth from 40 to 90. I tried using
table(Life.Expectancies.at.Birth) to show the frequencies of each
number and
I do not know how to continue.
