thank you for your response. here it is the piece of R code : given 3 data

how shall I integrate N, a

Dear all,
please could you advise on the R code I could use in order to do the
following operation :

Thank you Duncan and Rui for your time and interest in this issue.
Maybe it is a problem with Windows 7 and Spanish, and not Windows 10.
Let's wait for someone with the same enviroment, before assuming it's a
problem with my PC/configuration.

For what it's worth, I tried setting my Region | Formats setting to
Spanish (Peru) in Windows 10 Control Panel, and got Spanish weekday and
month results.
I believe on Windows we use the Microsoft C strftime function to produce
these strings, with the %A (for weekday) or %B (for month) formats
Hello,
This doesn't answer the question, but in portuguese it works as expected.

Hi,
I want to reporte some strange behaviour with the "months" function, from
base R.
When using "months" to extract months from a date column, I'm getting the
months in english, when I was expecting months in spanish.
When using "weekdays" to extract days of week from a date column, I'm
getting
This appears to be a case of insufficient understanding of statistics, which is
not on topic for r-help. Look at how well the per-firm models would work... my
guess is that some of the firms have insufficient data for useful analysis. If
that is not it, consider providing a more concrete example

Your function has mismatching parentheses.
I recommend using a computer algebra system like Maxima.

Hi ,
I'm asking for a way to compute the integral of: function(x)
{x*(log(x)+b)*((log(x)+b)^(a-1)-b^(a-1))/(a-1)*(b^(a-1)}
When a and b are between 1 to 10 and X is the integral parameter between 0 to 1
