getWinProgressBar does not return previous value
I am trying to use winProgressBar, however I find that although
setWinProgressBar updates the value on the screen, getWinProgressBar does
not return this value.
E.g
> pb <- winProgressBar()
> setWinProgressBar(pb, 0.2)
> getWinProgressBar(pb)
[1] 0
I tried the same with tkProgressBar, and it is working as I would expect
from the documentation.

improving/speeding up a very large, slow simulation
Dear R help;
I'll preface this by saying that the example I've provided below is pretty
long, turgid, and otherwise a deep dive into a series of functions I wrote
for a simulation study. It is, however, reproducible and self-contained.
I'm trying to do my first simulation study that's quite big, and so I'll
say that the output of this simulation as I'd like it to be is

Procesos paralelos
Hola:
Vuelvo a la carga con algo que resolví hace años y que ahora me ha dejado de funcionar y no consigo arreglar. A ver si alguien me sugiere algún enfoque o directamente la solucion.
Utilizo R en muchos procesos ETL y la cuestión es que me encuentro con que tengo que hacer inserts en un BBDD de SQL Server de varios miles (a veces millones de registros) que mientras R las realiza parece que

Confusing error message for [[.factor (PR#14209)

Procesos paralelos
Hola, ¿qué tal?
Si la base de datos de destino es SQL Server, ¿por qué no pruebas con
la función dbBulkCopy del paquete
https://github.com/agstudy/rsqlserver? Debería poder cargar millones
de registros en segundos. Al menos, en una única transacción en lugar
de múltiples como con sqlSave.
Un saludo,

Estimado Gilsanz
Algo que puede ser, ¿tiene instalado tcltk en Windows?
Yo ante un problema parecido lo solucioné realizando un contador, en mi caso conozco la cantidad de consultas, entonces simplemente ?imprimo? en pantalla 1 de 100, 2 de 100, etc. No es gráfico, pero R me informa dos cosas, que está trabajando y cuánto falta, feo a la vista pero muy simple.

loess() crashes R on my system
Greetings and happy new year!
I am in the process of converting some of the old S-PLUS scripts from
Visualizing Data (Cleveland, 1993)
into lattice. In fact, I did most of it several years ago, and at the time,
all of the scripts that contained
loess() worked fine. Tonight, I ran most of the scripts again, but every one
that I tried with a
loess() call crashed R. I tried it in two sessions, one

Documentation: format of read.table help text (PR#14180)
Dear R developers,
I find the format of descriptions of the arguments in the read.table
help text slightly inconsistent.
For example, the logical arguments comes in seven different formats,
more or less explicit about the consequences of a TRUE (or FALSE):
1. check.names logical. If TRUE then the names...
2. blank.lines.skip logical: if TRUE blank lines...
3. flush logical: if TRUE,

Dang! Does that mean it'll return errors for the statistical idiocy I

Use of processor by R 32bit on a 64bit machine
Dear all,
I've recently purchased a new 64bit system with an intel i7 quadcore
processor. As I understood (maybe wrongly) that to date the 32bit
version of R is more stable than the 64bit, I installed the 32bit
version and am happily using it ever since. Now I'm running a whole
lot of models, which goes smoothly, and I thought out of curiosity to
check how much processor I'm using. I

How to read.table with “Hebrew” column names (in R)?
(I am reposting this question after a few months without a solution...)
Hi all,
I am trying to read a .txt file, with Hebrew column names, but without
success.
I uploaded an example file to: http://www.talgalili.com/files/aa.txt
And tried the command:
read.table("http://www.talgalili.com/files/aa.txt", header = T, sep = "\t")
This returns me with:

predict.kohonen for SOM returns NA?
All,
The kohonen predict function is returning NA for SOM predictions
regardless of data used... even the package example for a SOM using
wine data is returning NA's
Does anyone have a working example SOM. Also, what is the purpose of
trainY, what would be the dependent data for an unsupervised SOM?
As may be apparent to you by my questions, I am very new to kohonen
maps and am very grateful

Compare two data frames
I wonder if there is a more efficient way to do this task. Suppose I have two data frames, such as
d1 <- data.frame(x = c(1,2,3), y = c(4,5,6), z = c(7,8,9))
d2 <- d1[, c('y', 'x')]
The first dataframe d1 has more variables than d2 and the variable columns are in a different order.
So, what I want to do is compare the two frames on the variables that are common between

extracat , JGR, iWidgets install problems
