Hello everybody
If
R a - 1i+(1:10)
I would like to say
R Im(a) - 1:10
R a

But there does not seem to be a Im- function.
How about this:

If I wanna change the last 3 colunm namesd e f respectively into x y

colnames(df[4:6])-c(x,y,z)
But no change to the colnames of df.
And if I

You might need to install devel package(s) for X, which contain header files
that are needed. When configure finished, do you see `X11' among the final

I'm not sure where is/are your mistake(s). But you could try finding
whether you installed the MySQL shared libraries (as of 4.1.8 there
are separate RPMs for these), and/or whether you need to add to your
