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".
Why don't you run str(daten) on the data.frame to see what you actually imported? It's a good idea to always run a str() after reading data. And I wouldn't use 'real' as a colClass (although it does have an 'as' method); I don't see it mentioned on the help page for read.table. Peter Ehlers
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
