When reading the Pnad 2016, I executed the code below, in r studio

# Ler o dicionário de variáveis com as posições
#devtools::install_github("tidyverse/readr")

library(readxl)
library(dplyr)
library(readr)

dic = read_xls("dicionario_das_variaveis_PNAD_Continua_microdados.xls", 
skip=4, 
           col_names = F)
dic = dic %>% select(1:3) %>% na.omit
dic$inicio = as.integer(dic$inicio)
names(dic) = c("inicio", "tamanho", "nome")
dic

# Lendo a PNAD
# Primeiro, vamos definir um objeto com o formato das variáveis de interesse
 ?read_fwf
 posicoes = fwf_positions(start = dic$inicio, end = dic$inicio + (dic$tamanho - 1),
                     col_names = dic$nome)
posicoes$begin = posicoes$begin + 1

pnad16.1 = read_fwf("PNADC_012016_20180816.txt", col_positions = posicoes)

But in the end, the program does not run and presents the error:

Error in guess_types_(datasource, tokenizer, locale, n = guess_max) : 
Begin offset (5) must be smaller than end offset (5)

I appreciate help!!

  • Danielle, the dictionary you are using may not be from this PNAD report. Try downloading the dictionary from the same address you downloaded Pnad. https://servicodados.ibge.gov.br/download/DownloadArvore.aspx?f=1&camio=Trabalho_e_Rendimento/Pesquisa_nacional_por_amostra_de_domicilios_continua/Trimestral/Microdados/2016

There is a package created to facilitate the download and reading of microdata from Brazil. The package is called microdadosBrasil and still not in the CRAN. To lower it rotate:

# Precisa ter o pacote devtools instalado
devtools::install_github("lucasmation/microdadosBrasil")

Using this package reading the 2016 Continuous PNAD data is as difficult as:

library(microdadosBrasil)
download_sourceData("PnadContinua", "2016-anual-1v", unzip = TRUE)
pessoas <- read_PNADcontinua("pessoas", "2016-anual-1v")
head(names(pessoas))

[1] "Year" "Quarter" "UF" "Capital" "RM_RIDE" "UPA"

For more package options see the function documentation?read_PNADcontinua, or visit the README of the project, available at english or in portuguese (a little outdated).
