[R] Help with a code in R

Erika,
The code you sent is missing some matching braces. For example, see this pair of lines:
forecast_nal <- rbind.data.frame(forecast_nal, fct)
}
I do not see a left brace anywhere before this right brace.
Without the content of the data structures datos, calendar and espejo from the three files, we will not be able to reproduce your code. Often you can use only a small subset of the data and reproduce a problem, but only you will be able to find out how much of the data are sufficient to reproduce the problem.
You could start by trying to produce the problem with a minimum amount of data. Try something along these lines:
datos <- read.csv("C:/Users/ErikaRocío/Documents/Curso
R/FCST_YEAR_WEEK_PROD_NAC.csv")
b <- data.frame(datos)[1:10, ]
calendar <-
read.csv("C:/Users/ErikaRocío/Documents/Curso R/cat_sem.csv")
forecast_date <- calendar[1:10, c(8, 9, 14, 10)]
espejo <-
read.csv("C:/Users/ErikaRocío/Documents/Curso R/cat_prod.csv")[1:10, ]
Then use these short versions of the dataframes in the rest of your code and see if you get the same error. You will likely have to play with the number of rows in each dataframe to fine the smallest number that will work. When you discover the smallest dataframes that recreate the error, you can send us the output from dput() as shown below:
datos <- read.csv("C:/Users/ErikaRocío/Documents/Curso
R/FCST_YEAR_WEEK_PROD_NAC.csv")
b <- data.frame(datos)
dput(b[1:10, ])
calendar <-
read.csv("C:/Users/ErikaRocío/Documents/Curso R/cat_sem.csv")
forecast_date <- calendar[, c(8, 9, 14, 10)]
dput(forecast_date[1:10, ])
espejo <-
read.csv("C:/Users/ErikaRocío/Documents/Curso R/cat_prod.csv")
dput(espejo[1:10, ])
