Hi,
Try:
lines1 <- readLines("Garbage.txt",warn=FALSE)
dat1 <-
read.table(text=gsub("\t+","\t",lines1),stringsAsFactors=FALSE,sep="\t",check.names=FALSE,header=TRUE)
str(dat1)
#'data.frame': 10 obs. of 3 variables:
# $ Material : chr "Food Scraps" "Glass" "Metals" "Paper" ...
# $ Weight(Million Tons): num 25.9 12.8 18 86.7 24.7 ...
# $ Percent : num 11.2 5.5 7.8 37.4 10.7 6.8 5.5 11.9 3.2 100
jpeg("garbageweight.jpg",width=800)
barplot(dat1[-10,2],names.arg=dat1[-10,1],ylab=colnames(dat1)[2],col=rainbow(9),main="American
garbage")
dev.off()
A.K.
Hello guys, I'm having this weird problem with my assignment. I can't seem to
import the data that I have created.
I keep getting an error that says "Error: More Columns than Column names"
This is my data file.
Garbage.txt
Was also wondering if you guys could send me into the right direction on how to
do this.
1. Create a data frame with the data given above.
2. Create the bar plot for weight variable with appropriate labels. Resize the
graphics
panel/ window so that all labels are visible.
3. Add colors. Suppose n is the number of bars.
> barplot(..., col = rainbow(n))
4. Save the plot to garbageweight.jpg
This is how it's supposed to look like at the end.
