Hi Pedro,
Assuming that you get a vector of daily percentage changes:
dpc<-c(+3.1, -2.8, +1.7, +2.1)
get the cumulative change and add 100:
cumsum(dpc)+100
[1] 103.1 100.3 102.0 104.1
You can then plot that. As Rui noted, your mail client is inserting
invisible characters that prevent cutting

Edit the Roxygen2 comments in your R source code, or just don't use

Hello,
The functions are not equivalent.
integrate subdivides the interval lower = 0, upper = 10 in into a
maximum subdivisions = 100L. If you print length(X) you will see that
it's 21.
X is a vector of 21 values and to compute X^(1:10) this expands to
X[1]^1, X[2]^2, ..., X[10]^10, X[11]^1,
No.
Post to r-package-devel for help with R packages.
However, roxygen2 is an Rstudio supported package, and you may need to post
on Rstudio's site for help on it.

Hola Ricardo,
En estos casos, vas a poder visualizar mejor las distribuciones si usas
gráficos del tipo "violinplots".
Son especialmente útiles para poder visualizar cambios en distribuciones en
el tiempo.
Otra alternativa con la que puedes ver estas diferencias es con los
gráficos del paquete
Hola,
Para los gráficos puedes cambiar a escala logarítmica (si los atípicos están
por arriba) o alguna otra transformación.
Para la comparación puedes intentar hacer un test de Kruskal-Wallis
Un saludo,

Hola amigos buenas noches. Estoy intentando comparar la distribución de una misma variable continúa pero en dos lapsos de tiempo diferentes. Lo malo es que los datos son demasiados atípicos y a través de box plots no se puede apreciar por la gran cantidad de atípicos que hay, lo que hace que las
13 matches
