Hi,
to get the residuals and coefficients I did the following:
kurse <- read.table("kurse.txt" header=T)
the data:
index bmw mru rwe vow kar sie bas
1 159,70 74,18 338,21 89,03 110,30 141,23 178,53 67,97
2 160,76 73,46 343,66 89,38 110,30 142,66 180,45 68,30
3 162,45 74,18 349,12 91,54 108,54 146,22 183,12 68,85
4 162,18 72,74 349,12 92,20 106,43 144,80 181,75 68,52
5 161,64 72,98 340,93 91,43 101,87 144,08 181,41 68,30
lm(index ~ bmw + mru + rwe + vow + kar + sie + bas,
data=kurse)
But instead of getting the coefficients R is giving me this:
(Intercept) kurse$bmw68,92 kurse$bmw69,39 kurse$bmw69,54
2.00 3.00 4.75 1.00
kurse$bmw69,63 kurse$bmw69,87 kurse$bmw70,11 kurse$bmw70,35
8.00 14.00 10.00 7.50
...... and so on
Warning message:
"-" not meaningful for factors in: Ops.factor(y, z$residuals)
Please help. The function is maybe important for my exam.

read.table() has a paramter called 'dec' which specifies the decimal separator. You probably want to set dec = "," in your read.table() call. -roger _______________________________ UCLA Department of Statistics rpeng at stat.ucla.edu http://www.stat.ucla.edu/~rpeng On Mon, 17 Jun 2002, Frithjof Weinert wrote:> Hi, > > to get the residuals and coefficients I did the following: > > kurse <- read.table("kurse.txt" header=T) > > the data: > > index bmw mru rwe vow kar sie bas > 1 159,70 74,18 338,21 89,03 110,30 141,23 178,53 67,97 > 2 160,76 73,46 343,66 89,38 110,30 142,66 180,45 68,30 > 3 162,45 74,18 349,12 91,54 108,54 146,22 183,12 68,85 > 4 162,18 72,74 349,12 92,20 106,43 144,80 181,75 68,52 > 5 161,64 72,98 340,93 91,43 101,87 144,08 181,41 68,30 > > lm(index ~ bmw + mru + rwe + vow + kar + sie + bas, > data=kurse) > > But instead of getting the coefficients R is giving me this: > > (Intercept) kurse$bmw68,92 kurse$bmw69,39 kurse$bmw69,54 > 2.00 3.00 4.75 1.00 > kurse$bmw69,63 kurse$bmw69,87 kurse$bmw70,11 kurse$bmw70,35 > 8.00 14.00 10.00 7.50 > ...... and so on > > Warning message: > "-" not meaningful for factors in: Ops.factor(y, z$residuals) > > Please help.
