Dear R users,
I recently stumbled upon problems of reproducibility while running GAM analyses
in different R and gam package versions. In the example below, a small dataset
is created in which the y and x1 variables are 100% correlated. The intents of
this example were primarily for regression
You are constructing the equivalent of a two-line data file, and complaining
that it is not treating it like it was one line. If it did used to accept this
silently [skeptical] then I for one am glad it produces a warning now.

To be specific, the effect of loading packages with the "library" function is
NOT saved when you save the workspace... and if you come back much later after
you have updated some packages the old saved objects may not work well with
those new packages. At the very least you have to re-load all n
This doesn't make sense to me:

Suggestion:
Read the "Intro to R tutorial" that ships with R. Alternatively, there are
also many good online tutorials, some free, some not. You'll need to spend
some time and effort to learn R's basic data structures and paradigms even
if you don't get involved in any serious programming.

Hi Jon,
Saving your workspace doesn't mean that everything will be rerun when
you start a new R session. I just means that persistent objects like
data frames will be there. If you type:
objects()
you will see all of those things that were there when you ended in the
last session. Things like com
Hello,
I recently downloaded R in hopes of learning to use it for statistics.
I have promptly run into a problem, as I am unable to save, and later recover,
a workspace so I can resume work where I left off.
I am using Windows.
I indicate "yes" to the pop up after q(). Then when I later reopen

I noticed that starting with R version 3.3.0 onward, this generates a
warning:
> txt <- c("a", "3.14")
> read.table(file = textConnection(txt), header = FALSE, colClasses
= c(x = "character", y = "numeric"))
the warning is "not all columns named in 'colClasses' exist" and I gues
Before going to stackexchange you should consider if a square root
transformation is appropriate for the model that you are trying to
estimate. If you do so, you may be able to interpret the coefficients
yourself. If no explanation is obvious you probably should not be using a
square root transform
Hello,
I think that your code is simple enough to be considered "nice". If you
are worried about the for loop, don't, were loops worrying they wouldn't
exist.
Hope this helps,

This will give you a list of the current base packages:
priority <- installed.packages()[,"Priority"]
names(priority)[priority %in% "base"]
Change "base" to "recommended" to see the current recommended packages.
The base packages are part of R, they are not available separately. If you try

I have a list of file names, and a list of data frames contained in those files.

Every file contains two columns.

Using quantiles does not imply assumption of normality, unless you drag that
assumption in separately. Please go review statistics again, offlist, and come
back when you need help with R.
