substitution of the ASCII character "squared" AKA "^2" AKA (alt+0178) with a tractable one
...other (running on win XP) which process the data is connected to the first one via serial. I get the data from this last computer. The string I'm trying to process comes from a command like this > myString <- readLines(path.to.file, 150)[78] and looks like this > [1] "(MPa)\t(mm3)\t(nM)\t(mm3/g)\t(mm3/g)\t(%)\t(m\xb2/g)\t" where "\xb2" is the alt+0178 ASCII character My problem is to find out the regexp to substitute the ASCII 0178 with a simple "2" No problem with, say gsub('\t',';', myString) [1] "(MPa);(mm3);(nM);(mm3/...

Calling update on an lm-object inside a function
...ntercept) x 0.1 1.1 Question: Is this the "appropriate" way of making such a model "available" for an update inside a function, or is there a better way? I guess so - because: If I change the model formula of my model and then invoke foo2 I get mm3 <- update(mm,.~.-x) > foo2(mm3) Error in eval(expr, envir, enclos) : object 'y3' not found This puzzles me. Question: can anyone help me clarify why this happens and what I can do to fix it. Thanks in advance S?ren
