question of merging two dataframes
Suppose I have two data frames A and B
A has three variables and B also has three variables.
I would like to merge these two database but the requirement to merge
is that the value of the second column in database A is less than the
value of the second column in database B. Is there a R code to do
this? Thanks
Dataframe A: V1a V2a V3a

Repating a loop of lm function with different columns of database
Hi,
First let me thank you for the incredible help and resource that this forum is.
I am trying to compare the repeated measurement of more than 100 analytes that have been take in 70 subjects at 2 time points adjusted for the time difference of sample times(TimeDifferenceDays), therefore I wanted to do it with a function that allows me to do all at once. (131 is the column difference that

Manipulation of longitudinal data by row
I have a dataset of the form below, consisting of one unique ID per
row, followed by a series of visit dates. At each visit there are
values for 3 dichotomous variables. Of the 8 different possible
combinations of the three variables, 4 are "abnormal" and the
remaining 4 are "normal". Everyone starts out abnormal, and then
either continues to be abnormal at subsequent visits,

Expresión en un objeto
Esta es la respuesta que te da ChatGPT-4:
Entiendo tu pregunta y, aunque no hay una función nativa en R que te
permita hacer exactamente lo que estás pidiendo, puedes lograr el mismo
resultado utilizando una función. Una función te permitiría encapsular la
lógica de la expresión que quieres reutilizar y luego llamar a esa función
donde sea necesario.
He aquí cómo podrías hacerlo:

A ver... con que xfunc() esté preparada para tomar un parámetro de tipo "carácter" y evaluarlo, claro que se puede hacer...
Si el problema lo tienes en evaluar la expresión, la función "eval()" te lo hace.
Si no te he entendido bien, explícate más ?

Hola a todos:
Se me ha planteado un problema que no está ligado a ningún problema
concreto. Es más teórico.
Supongamos que tenemos tres variables:
V1 <- c (47, 71, 41, 23, 83, 152, 82, 8, 160, 18)
V2a <- c (NA, 36, 15, 5, 56, 18, NA, 5, NA, 5)
V2b <- c (37, NA, 15, NA, NA, NA, 90, NA, 161, NA)

Resultado de la consola como un tibble
Hola,
No hace falta (en este caso) capturarlo de la consola.
El resultado de la función apply se puede capturar y procesar.

Hola,
Bueno, puedes hacer el cálculo de una forma mucho más compacta y rápida.
Esta forma es especialmente recomendable cuando tienes muchas columnas y
muchas filas.

Inaccuracy in seq() function (PR#7503)
Full_Name: Vlad Stolin

OS: Windows 2000
Submission from: (NULL) (204.128.232.211)
When generating the sequence using seq() function with non-integer numbers
result is somewhat unpredictable. Example:

> v2<-c(1.60,1.65,1.70,1.75,1.80,1.85,1.90)

bwplot change whiskers position to percentile 5 and P95
Dear R-community,
Using bwplot, how can I put the whiskers at percentile 5 and percentile 95,
in place of the default position coef=1.5??
Using panel=panel.bwstrip, whiskerpos=0.05, from the package agsemisc gives
satisfaction, but changes the appearance of my boxplot and works with an old
version of R, what I don’t want, and I didn’t find the option in
box.umbrella parameters
Many thanks

cbind order
Hello
I need to use this command:
cbind(ftable(xtabs(cnt~geo+slp+con+hey,data=dt3))
hey is in count of success /failure value
but cbind gives failure/success counts. I want to change the order of
this cbind as success /failure counts.
for instance:
I want cbind to give counts as 32-4552 rather than 4552-32
what should I do ?
thanks in advance

restricted coefficient and factor in linear regression.
Hi,
my data set is data.frame(id, yr, y, l, e, k).
I would like to estimate Lee and Schmidts (1993, OUP) model in R.

** di# and dt# are dummy variables for industry and time **
