Hi,
I have a data frame that looks like this:
ID
Var
Var2
Var3
xxx
100
909
920
yyy
110
720
710
zzz
140
680
690
I can load the file and produce a plot from values from one column.
> data <- read.csv("test.csv")
> barplot(data$Var2)
So far it's fine.
The data frame however has more columns with integer values in reality and I
want to plot from consecutive values of the SAME ROW.
Something like:
> barplot(data[1, 2:3])
or more generic:
> barplot(data[row.id, from.field:to.field])
Unfortunately this no longer is a vector! I understand that it could contain
non-numeric values which in my data frame is not the case.
How can I convert a "horizontal" one-line-data-frame into a vector?
Any help appreciated,
best regards,
Jörg
