谁能帮我找出我在这段代码中的错误在哪里？这就是我得到的：“错误：“}”中的意外'}'”

如果我尝试只运行循环下的块，一切都很好，但我需要在 50 页中处理它，然后合并。

library(pdftools)
library(tidyr)
library(sqldf)

sDirectorio = "/Users/muribe/Desktop"

archivoPDF = pdftools::pdf_text(file.path(sDirectorio,"centros_votacion.pdf"))

n = 0

WHILE (n <8) {
        n=n+1
        
        vLineas = unlist( strsplit(archivoPDF[n], split = c("\r\n")) )

        dfDefinicionTabla = data.frame( Orden  = 1:9,
                                        Campo  = c("Codigo","Provincia","Canton","Distrito","JRVInicial","JRVFinal","TotalJRV","TipoCentro","CentroVotacion"),
                                        Inicio = c(1,8,21,36,75,86,97,104,127),
                                        Fin    = c(7,20,35,74,85,96,103,126,180),
                                        Tipo   = c("numeric","character","character","character","numeric","numeric","numeric","character","character"),
                                        stringsAsFactors = FALSE)

        dfTabla = data.frame()
       
        for (linea in 7:length(vLineas)) {
          
          dfFila = data.frame(n, stringsAsFactors = FALSE)
          for (campo in 1:nrow(dfDefinicionTabla)){
            # campo = 2
            # Extrae cada uno de los campos de la linea  
            dfFila =cbind(dfFila, trimws(substr( vLineas[linea], 
                                                 dfDefinicionTabla[campo,]$Inicio, 
                                                 dfDefinicionTabla[campo,]$Fin), 
                                         which = "both") 
            )
            
          }
  
          colnames(dfFila)[2:(nrow(dfDefinicionTabla)+1)] = dfDefinicionTabla$Campo
          
          dfTabla <- rbind(dfTabla, dfFila)
        }

        }

print(dfTabla)``

谢谢，我将其更改为“重复”循环并修复了其他语法错误现在正在工作。
