Hi,

I am having some troubles installing the Rbloomberg package.
When I try to run library(Rbloomberg) I get the following message:

Carregando pacotes exigidos: rJava
Error : .onLoad falhou em loadNamespace() para 'rJava', detalhes:
?chamada: stop("No CurrentVersion entry in '", key, "'! Try re-installing Java and make sure R and Java have matching architectures.")
?erro: objeto 'key' n?o encontrado
Al?m disso: Mensagens de aviso perdidas:
pacote 'rJava' foi compilado na vers?o do R 2.13.2
Erro: pacote 'rJava' n?o p?de ser carregado

I don?t have any idea how to solve that. Anyone can help me ?
Thanks in advance

Hi Eduardo,

Apologies, but my Portuguese (?) is a bit rusty. If you can
temporarily switch the language to English that would make it easier
for me to understand the error messages.

Also, please run these commands and send the results:
sessionInfo()
installed.packages()[c("rJava", "RBloomberg"), ]

Thanks,
John

Hi there:

I am practicing the new R package DEoptim and following the paper titled
?Large-scale portfolio optimization with DEoptim? as attached.

I am wondering if there is error in this package or else because when I
tried the commands listed in Section 6. Portfolio optimization with DEoptim
but encountered some error message as listed below:
Error in NextMethod(.Generic) : dims [product 121] do not match the length
of object [40401]
Also : Warning message: In `-.default`(0.5 * dmvnorm(x, c(-3, -3)) + 0.5 *
dmvnorm(x, c(3,? : ??longer object length is not a multiple of shorter
object length

Could somebody share some hint or help?

Thank you for your kind consideration and response.

Thanks for your prompt reply.

It get stuck in the first block of the commands listed in Section 6. It
works fine before that block.
