Paul,
Perhaps slightly better and more concise is
y <- -x + 1
Why multiply? Of course it may be optimized in some cases.

Wow! Amazing stuff.
It will take me a while to digest all that you have offered here.
I came up with a simple solution myself:
y<- (-1*x)+1
Thank you

Thank you.
I came up with a slightly more complicated solution than yours myself:
y<- (-1*x) +1
I did not realize that adding a scalar to a vector would add that scalar to
each element of the vector. Nice!

The obvious answer is 1-x.
Another answer, which is good for converting any 0..n elements to any others,
is c(1,0)[x+1].
But the most important questions are
- where did x come from?
- what does it mean?
- why do you want to do this?
- what do you already know about R? Do you understand vector
Surely doing
y <- 1 - x
would be the simplest way?

Can you point me at any packages that allow users to write a
formula with coefficients?
I want to write a data simulator that has a matrix X with lots
of columns, and then users can generate predictive models
by entering a formula that uses some of the variables, allowing
interactions, like

Hello!
The following (which is a toy example) works fine, but I wonder if there is
a better or more elegant way than to do the loop:
xz <- vector("list",length=4)
x <- 6:9
for(i in 1:4)xz[[i]] <- x[i]
xz

[1] 6

Create a new variable using the `interaction`-function, apply you contrasts to
that object,
Hi Tom
I know the post is over 7-8 years old but I am having the same question. How to
do a post-hoc test like TukeyHSD on coxph type output.
Have you received any info in this matter?

Dear members,
We all know the power and usefulness of TA-Lib. There is a python wrapper for
it but, despite all my searching, I am unable to find it for R. Does anyone
know why? I am starting learning and using RStudio and would really like to be
able to call the TA-Lib functions from RStudio.
As the Wikipedia page you took your example problem from explains, the sets
cover problem can be formulated as an integer linear programming problem.
In R, such problems will be solved effectively applying one of the available
MILP packages, for example LPsolve or Rsymphony.

I am looking for an R package that solves Set Cover Problem. As Wikipedia
explains:
Given a set of elements [image: \{1,2,...,m\}] (called the universe) and a
set [image: S] of [image: n] sets whose union equals the universe, the set
cover problem is to identify the smallest subset of [image: S] w

Dear all,
Sorry that I am not sure that whether I should ask the question here or
R-devel. Is there any existed packages which implements or is implementing
feature hashing or similar function?
For who does not know "feature hashing", please let me give a brief
explanation here.
Feature hashing
Although there is a great deal of value to be gained by understanding how
"package" code is written, most of my R "projects" consist of a file with
10-100 lines of code working with data in the global environment that call on
packages. Such code is not typically posted online.
I do find it conv

I am bit new in R. I am looking for a code repository of few projects

I want to see them to learn more.
If any one of the esteemed members of the group may kindly help.

Hi,

The answer to this example is x = 2, but I'm looking for solutions when x

algebraic solution for x, unless I'm mistaken. Do

Dear R community,
Please let me know if there is an R data set with time to multiple outcomes
(unordered failure events of different types).
I am specifically looking for non-competing risks so that I can have observed
