I am trying to automatically produce a series of histograms from every column
of data frame with many columns.
The columns names of a shortened from of the data frame follow:
colnames<-names(smdata)

Colleagues,
I used the fix() function to edit an existing function when using RStudio.
After editing the function, I am given the option to SAVE the modified
function. I would like to know (1) where the modified function is stored (the

I need to define three vectors x, y, z (each of length 100) such that the
pair-wise correlations of the vectors have per-defined values r1 and r2. More
specifically I need to define x, y, and z so that:
corr(x,y) = r1
corr(y,z) = r2
Is there any easy way to accomplish this with R?
Thank you
