Estou usando um script criado por mim a partir das dicas da própria lista: <a href="http://r-br.2285057.n4.nabble.com/R-br-r-baixando-dados-inmet-td4660459.html" rel="nofollow" link="external" target="_blank">http://r-br.2285057.n4.nabble.com/R-br-r-baixando-dados-inmet-td4660459.html</a> na qual usei o código como template para automatizar o download dos dados do inmet. Infelizmente estou com alguns problemas, um deles é que só consigo usar o código no Windows, ou seja, no R do Windows e não do Linux (possuo o Windows 10 e o Ubuntu 16.04 no meu notebook).<u></u><u></u></span></p><p class="MsoNormal"><span lang="PT-BR"><u></u> <u></u></span></p><p class="MsoNormal"><span lang="PT-BR">Os erros no meu Linux são referentes a biblioteca RCurl que mesmo reinstalado várias vezes e usado com a biblioteca bitops continuam a não funcionar. Outro problema que tenho é o não conhecimento sobre como salvar os arquivos baixados em um .txt ao invés de alocar em variáveis como estou fazendo. Caso algum de vcs se interesse em mexer e melhorar o código segue ele abaixo:<u></u><u></u></span></p><p class="MsoNormal"><span lang="PT-BR"><u></u> <u></u></span></p><p class="MsoNormal"><span
