: Hi, 
: 
: I'm now to R and hope (actually, I'm quite sure) you can help me. I made 
: an experiment and measured two values. As I know the errors of these 
: values I want to use them with the linear regression, 
: eg 
: Value A 
: 1.1+-0.02 
: 1.9+-0.05 
: 3.05+-0.03 
: 4.0+-0.01 
: 5.1+-0.06 
: 
: Value B 
: 4.2+-0.14 
: 5.3+-0.05 
: 6.8+-0.11 
: 7.9+-0.01 
: 8.5+-0.02 
: 
: lm(B~A) does the linear regression but how can I use the fact that 1.1 is 
: between 1.12 and 1.08? 
: How can I put error bars for A and B in the plot (like Excel is capable 
: of)? 
: 
: I hope I made myself understandable, 
: thanks
