Looking for a function or a set of steps
Paul,
Perhaps slightly better and more concise is
y <- -x + 1
Why multiply? Of course it may be optimized in some cases.

Hello,
You are right, I didn't think about that one.
Here is another, esoteric, way.
With `+` substituting for as.integer:
+!x
Hope this helps,

Hello,
And a test for equality of all solutions so far.
do.call(
   identical,
   list(
     1L - x,
     +!x,
     as.integer(!x),
     as.integer(xor(x, 1L))
   )
)
#> [1] TRUE
Hope this helps,

Rolf,
If it is homework, I have to wonder at what level the class is before any of the proposed answers would be considered acceptable by the instructor. For a true beginner who has not even learned that much of R is vectorized, we are back to perhaps using a manual loop with indices and ...
I will say that these days, I see too many assignments handed in by novices, such as 12-year-old kids

Looking for simple line-splitting code
If I have this object:
   x <- c("abc\ndef", "", "ghi")
and I write it to a file using `writeLines(x, "test.txt")`, my text 
editor sees a 5 line file:
   1: abc
   2: def
   3:
   4: ghi
   5:
which is what I'd expect:  the last line in the editor is empty.  If I 
use `readLines("test.txt")` on that file, I get the vector

Hi Duncan,
Thanks for your comment, I agree with that.
But, how it can be justified that an Optimizer gives a result which is
inferior to the starting value? At most, resulting value can remain at the
same level, isnt it?

A 3rd option could be
scan(text=x, what="", blank.lines.skip=FALSE)
(all because readLines() doesn't obey the text=x convention, perhaps it should? I'm unsure whether the textConnection is left open in Rui's method.)

DPLYR Multiple Mutate Statements On Same DataFrame
Hi R Helpers,
I have been looking for an example of how to execute different dplyr mutate statements on the same dataframe in a single step.  I show how to do what I want to do by going from df0 to df1 to df2 to df3 by applying a mutate statement to each dataframe in sequence, but I would like to know if there is a way to execute this in a single step; so simply go from df0 to df1 while executing

Problem with minimization that I failed to understand
My code is to minimize the objective function
therefore, shouldnt I expect that
StartingValue = c(0.12, 0.04, 0.07, 0.03, 0.06, 0.07, 0.07, 0.04, 0.09,
0.08, 0.02, 0.02, 0.03, 0.06, 0.02, 0, 0.07, 0.05, 0.02, 0.02, 0.02)
Fn(q1$par) < Fn(StartingValue)
## FALSE
Below is the corrected code that can be reproduced:
MyDat = structure(list(c(50L, 0L, 0L, 50L, 75L, 100L, 50L, 0L, 50L, 0L,

dput(treat)
I got advice here that I didn't understand! Can I ask to explain me the meaning of this procedure: first get the structure, and then assign it back. For what? Thanks!? (Great thanks to Moderator/Admin!)
You should learn to post in plain text and use dput to present your data structures. At your console do this
dput(treat)
# and this will appear. Copy it to your plain-text message:

An opinion question, please
Hello everyone!
I have an opinion question please.  If I?m writing a new package, would you
recommend using S3 or S4 structure, please?
I know I will get lots of opinions, but that?s fine.
Thanks,
