What is NYT? Is it a dataframe? Is "Title" a column? What exactly
are you wanting to plot? Is it just the values in column "B" where
"Title" is equal to "A"? The posting guide does suggest that you
provide a reproducible set of code/data. You can probably do what you
want if you can explain w
Sorry, forgot to attach the error it is giving me.
> if(NYT["Title"]=="A")
+ plot(NYT["B"],ylim=c(0,50),xlim=c(0,50),ylab="B",xlab="A")

the condition has length > 1 and only the first element will be used
Thank you

Hello all,
I've been able to separate the columns now so that when I call NYT[,9] it
gives me just that column. I'm still trying to plot however. When I used the
previous if()plot() statement it plots something, but its not what I want. I
want to plot the rank vs time, but its just plotting the sa

I think you need to put quotes around the column header name,
something like: NYT["Title"]
example:
> my.df <- data.frame(header1=1:3, header2=1:3)

Hi everyone,
I'm trying to plot some data across time. I have a list of articles, ranks,
date/times, authors, etc. Someone suggested using zoo and someone suggested
using ts. I'm pretty new at this and have been trying a simple if() plot()
statement, but it doesn't seem to work. I keep getting an
