Hi,
As there is not much information like str() or the data, it is difficult to comment.
But, try this (considering your x and y are factors):
x<-c("1","4","7","9","10","15")
?y<-c("3","5","8","6","5","14")
?dat1<-data.frame(x,y)
?str(dat1)
'data.frame':??? 6 obs. of? 2 variables:
?$ x: Factor w/ 6 levels "1","10","15",..: 1 4 5 6 2 3
?$ y: Factor w/ 5 levels "14","3","5","6",..: 2 3 5 4 3 1
dat2<-dat1
?dat2$x<-as.numeric(as.character(dat2$x) )
?is.numeric(dat2$x)
#[1] TRUE
?dat2$y<-as.numeric(as.character(dat2$y))
?is.numeric(dat2$y)
#[1] TRUE
#Now try plot
?x1<-dat2[,1]
?y1<-dat2[,2]
?plot(x1,y1)
Hope this helps.
A.K.

Subject: [R] Simple x,y Plot
Dear Community,
i have read in a table with two column from a *txt-File. What i get is a
data-frame wit two column.
After that i allocate this 2 column to x and y. Plotting this, i obtain a
picture that looks like a bar plot (something like a grid).
Is that because x and y is in factor-formatted? A conversion with
"asnumeric" doesnt work. I get a vector with "NA".
Here is my code:
daten<-read.table("C:/Users/Robert/Desktop/regen.txt", header=FALSE,
colClasses=c("real","real"))
x<-daten[,1]
y<-daten[,2]
plot(x,y)
Greetings
