Peter,
Interesting. Never heard of copying from the clipboard. I am also on a
MacBook Pro, but I cannot get it to work.
1. I selected the column of data (including the header) in Excel.
2. Selected Edit-Copy.
3. In R, tried:
a - read.delim(clipboard)

HI,
I guess you were talking about column names instead of rownames.
If you have a data like the one below to read:
dat1-read.table(text=
beta0 beta1 pvalor Crom
rs17 158.5980 12.252462 9.083193e-135 1
rs46 163.3730 3.304276 3.279925e-06 1
rs63
HI,
Try this:
subset(a,y==0)
# x y
#2 2 0
#5 5 0
#10 10 0
#or
subset(a,y%in%0)
# x y
#2 2 0
#5 5 0
#10 10 0
A.K.

Yes, the round(seq( )) sollution does it.
Many thanks to the sender of this (and other similar) solutions.

I have a question on the four parameter logistic regression.
Not sure about how to set the start values for the parameters.
Can anyone familiar with this give some hint? Thanks so much.

Thank you very much. grconvertX() and grconvertY() work very well.

Hi,
To my knowledge, Ryacas can do symbolic computation in R, like
Mathematica or Maple.
I wonder if it (or any other R package) can solve symbolically a system

Hi,
If I do a standard svm regression with e1071
x - seq(0.1, 5, by = 0.05)
y - log(x) + rnorm(x, sd = 0.2)
m - svm(x, y)
we can do predict(m,x) to get the fitted values. But what if I wan tho get them
by hand?
Seem to me like it should be
w = t(m$coefs)%*%m$SV
x.scaled = scale(x,
