Problems with installing the SSOAP package on R

Question

I’m trying to install the package SSOAP in the software R and receive as return the following error message:

ERROR: dependency 'Xmlschema' is not available for package 'SSOAP' * removing ' srvfcmfile/documents$/2437/My Documents/R/win-library/3.6/SSOAP' Warning in install.Packages : installation of package ːC:/Users/2437/Desktop/FORMAO~1/MACROE~1/61E21~1.MOD/SSOAP_0.9-0(1).tar.gz' had non-zero Exit status

I searched about the bug and the package and from what I understood this was removed.

The part of code I’m trying to run is this:

wsdl <- getURL("https://www3.bcb.gov.br/sgspub/JSP/sgsgeral/FachadaWSSGS.wsdl", 
           ssl.verifypeer = FALSE)
doc  <- xmlInternalTreeParse(wsdl)

def <- processWSDL(doc)
ff  <- genSOAPClientInterface(def = def)

processWSDL and genSOAPClientInterface depend on SSOAP.

I would like to know if there is any other package that replaces SSOAP so I can run what I need.

Answer 1

To install R packages that are not available for the R version you are running, go see if they are in cran files.

Then there are several ways to install these packages. I will assume that the user downloaded the files .tar.gz and that these are in a local directory.

The following works on Ubuntu 19.04.

old_dir <- getwd()
setwd('~/um/caminho/para/as/transferencias')

file_xmlschema <- list.files(pattern = '^XMLSchema_.*\\.tar\\.gz')
install.packages(file_xmlschema, repos = NULL, type = "source")

file_ssoap <- list.files(pattern = '^SSOAP_.*\\.tar\\.gz')
install.packages(file_ssoap, repos = NULL, type = "source")

setwd(old_dir)

Ready, the packages are installed. Now I will run the question code.

library(SSOAP)
library(RCurl)
library(XML)

wsdl <- getURL("https://www3.bcb.gov.br/sgspub/JSP/sgsgeral/FachadaWSSGS.wsdl", 
               ssl.verifypeer = FALSE)
doc  <- xmlInternalTreeParse(wsdl)

def <- processWSDL(doc)

There Were 12 warnings (use warnings() to see them)

All warning messages are identical. It means that the function code should be updated to provide a list without elements.

warnings()

Warning messages:
1: In Structure(unlist(v[i]), Names = sapply(v[i], Names)) : Calling 'Structure(NULL, *)' is deprecated, as NULL cannot have Attributes.
Consider 'Structure(list(), *)' Instead.

ff  <- genSOAPClientInterface(def = def)

Answer 2

library(XML)

library(RCurl)

old_dir <- getwd()
setwd('~/um/caminho/para/as/transferencias') #adicionei aqui o diretório utilizado, conforme me explicou acima.

file_xmlschema <- list.files(pattern = '^XMLSchema_.*\\.tar\\.gz')
install.packages(file_xmlschema, repos = NULL, type = "source")

file_ssoap <- list.files(pattern = '^SSOAP_.*\\.tar\\.gz')
install.packages(file_ssoap, repos = NULL, type = "source")

setwd(old_dir)

wsdl <- getURL("https://www3.bcb.gov.br/sgspub/JSP/sgsgeral/FachadaWSSGS.wsdl", 
               ssl.verifypeer = FALSE)
doc  <- xmlInternalTreeParse(wsdl)

def <- processWSDL(doc)
ff  <- genSOAPClientInterface(def = def)

inicio <- '01/01/1999'

fim <- '04/09/2015'

getSeries <- function(codigos, data.ini = inicio, data.fim = fim, remove.old = TRUE) {
  xmlstr <- ff@functions$getValoresSeriesXML(codigos, data.ini, data.fim, 
                                             .opts = list(ssl.verifypeer = FALSE))
  doc <- xmlInternalTreeParse(xmlstr)

  cleanup <- xpathApply(doc,"//SERIE", function(s) {
    id <- xmlGetAttr(s, "ID")
    s1 <- xmlSApply(s, function(x) xmlSApply(x, xmlValue))
    s1 <- t(s1)
    dimnames(s1) <- list(NULL, dimnames(s1)[[2]])
    df <- as.data.frame(s1, stringsAsFactors=FALSE)
    df$SERIE <- id
    df
  })
  df <- Reduce(rbind, cleanup)

  df$data  <- as.Date(sapply(strsplit(df$DATA,  "/"),
                             function(x) paste(c(x[2:1], 1), collapse="-")), "%Y-%m-%d")
  df$valor <- as.numeric(df$VALOR)
  df$serie <- factor(df$SERIE)

  if(remove.old){
    df$BLOQUEADO <- NULL
    df$SERIE <- NULL
    df$DATA <- NULL
    df$VALOR <- NULL
  }
  df
}

This is the code I need to run.
