: 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
: Sebastian
