Hello all,
I hope someone of you can help me out, I have searched other posts as well
but I can't find any solution to the problem I'm dealing with.
I want to make a histogram from the data Telephone Lines
MDGdataset <-read.csv("MDG_dataset_2010.csv", header=T)
MDGdatasetAdapted <- subset(MDGdataset, select = c(Country_Code,
Country_Name, Year, GNI.per.capita..Atlas.method..current.US..,
Telephone.lines..per.100.people., Internet.users..per.100.people.))
MDGdatasetAdapted
MDGdatasetAdapted <- na.omit(MDGdatasetAdapted)
names(MDGdatasetAdapted) <- c("Code","Country","Year","GNI","Telephone
Lines","Internet Users")
Then I do as follows:
hist(MDGdatasetAdapted$Telephone.Lines, ylab="Frequency", xlab="Telephone
Lines per 100 people", main="Frequency of telephone lines per 100 people",
nclass=100)
To give an example, the first 2 lines of the MDGdatasetAdapted dataset look
like this:
Country_Code Country_Name Year
GNI.per.capita..Atlas.method..current.US.. Telephone.lines..per.100.people.
Internet.users..per.100.people.
1 AFG Afghanistan 2010
410 0.1 3.7
What am I doing wrong for getting the message:
Error in hist.default(MDGdatasetAdapted$Telephone.Lines, ylab = "Frequency",
:
'x' must be numeric
??
Please help me out I would be eternally grateful
