sum() vs cumsum() implicit type coercion
Hi
I noticed a small inconsistency when using sum() vs cumsum()
I have a char-based series

a Bootstrap understanding problem
I tried to reproduce a result from a former colleague which he got
with S-plus bootstrap method. I don't have S-plus at hand.
In R, there are 2 packages related to bootstrap method, bootstrap and
boot. The former has a function called 'bootstrap' but this does not
seem to conform either to the function used in S-plus nor to that
described in MASS, 3d ed., p.144.
The latter seems to be

spam on R lists --> refuse mail??
We get caught occasionally, and we all receive spam;
sorry for the last one (on R-help). Of course, there will never be a 100%
sure prevention...
Question is what should happen when mail from R-help to an adressee
is refused with the following message : At least I won't be able to easily send
e-mail to them {and am not willing to use a non-easy way}....

R (>= 3.4.0): integer-to-double coercion in comparisons no longer done (a good thing)
Hi,
there was a memory improvement done in R going from R 3.3.3 to R 3.4.0
when it comes to comparing an integer 'x' an double 'y' (either may be
scalar or vector).
For example, in R 3.3.3, I get:
> getRversion()
[1] '3.3.3'
> x <- integer(1000)
> y <- double(1000)
> profmem::profmem(z <- (x < y))
Rprofmem memory profiling of:
z <- (x < y)

[nlme] BLUPs for a new subject in a fitted lme model?
I am seeking for a method to calculate, given a fitted lme model
and some data for a subject, the random effects predictors
for this subject. I can only find predictors for the subjects used in
creating the fit. Of course I could just add the subject and redo the fit.
But I want to avoid just this refitting.
Thanks for help

converting factor to numeric gives "NAs introduced by coercion"
Hi,
I have a dataframe that I imported from a .txt file by:
skogTemp <- read.delim2("Skogaryd_shoot_data.txt", header=TRUE, fill=TRUE)
and the data are factors, how can avoid factors from the beginning? Although
the file contains both characters and numbers.
I tried to convert some of the columns from factor to numeric and as I
understood it you can not use only as.numeric but

Coercion function does not work for the ALTREP object
Hi all,
The coercion function defined for the ALTREP object will not be called by R
when an assignment operation implicitly introduces coercion for a large
ALTREP object.
For example, If I create a vector of length 10, the ALTREP coercion
function seems to work fine.
```
> x <- 1:10
> y <- wrap_altrep(x)
> .Internal(inspect(y))

Hook into Coercion Framework for data.frame
Hi,
I am looking into a way to hook into the R coercion framework to allow
me to convert table-like data stored within a COM object into a
data.frame.
Some of our COM objects have their own table-like data storage, and from
R's point of view it's an object (EXTPTRSXP) decoarated with a sepcial
symbol so we can easily identify it.
COM_Table <- a_method_that_creates_the_object()

coercion
Dear ALL
I don't know why I can see this error in run this sentences.
In paste("V", 1L:cols, sep = "") : NAs introduced by coercion

I will be glad if you help me.

integer coercion when indexing and subsetting (PR#2430)
At the end of his bug report, Philippe says
PhGr> ..... Moreover, the subset operation [] uses as.integer() and
PhGr> consequently, can suffer from the same syndrome. A WARNING section in
PhGr> Extract.Rd would be welcome too.
[BTW: Thank you Philippe! ]
Currently, "Extract.Rd" does not say anything on the kind of

Coercion of 'exclude' in function 'factor' (was 'droplevels' inappropriate change)
I am basically fine with the change.
How about using just the following?
if(!is.character(exclude))
exclude <- as.vector(exclude, typeof(x)) # may result in NA
x <- as.character(x)
It looks simpler and is, more or less, equivalent.
In factor.Rd, in description of argument 'exclude', "(when \code{x} is a \code{factor} already)" can be removed.

automatic coercion to character
Hi R users
I am wondering how I can avoid automatic coercion of my numeric vector
elements to character
init <- c(age='N', R=as.numeric(0.5), S=as.numeric(0.8))
I have used as.numeric() but it does not seem to work
Thank you

NAs introduced by coercion in dist()
I work with Windows and use R version 2.4.1. I am JUST starting to learn this
program...
I get this warning message 'NAs introduced by coercion' while trying to
build a distance matrix (to be analyzed with NMDS later) from a 336 x 100
data matrix. The original matrix has lots of zeros and no missing values,
but I don't think this should matter.

Coercion/conversion of logical index to integer index
Hi all,
This question has significant potential to be a stupid one, but as I could find no hints in
the manual or previous posts:
If you have a logical index X:
>X
[1] TRUE FALSE TRUE TRUE FALSE
And you want an equivalent integer index Y:
>Y
[1] 1 3 4
Is there no easy way? (I'm thinking of the equivalent of FIND in Matlab)
