R Tools and pdftools not found

Archaeopteryx

Hi,

I've upgraded the sub version of 2020.3 ( can't upgrade further yet ) to allow R Tool and pdftools. 

I've installed the R Installer three times but I still receive the following error on all R Tools:

R (34) Error in loadNamespace(name) : there is no package called 'pdftools'
R (34) Execution halted
R (34) The R.exe exit code (1) indicated an error.

The following is how I configured the R Tools:

# read in the PDF file location which must
# be in a field called FullPath
data <- read.Alteryx("#1",mode="data.frame")

# Use pdf_text() function to return a character vector
# containing the text for each page of the PDF
txt <- pdftools::pdf_text(file.path(data$FullPath))

# convert the character vector to a data frame
df_txt <- data.frame(txt)

# output the data frame in steam 1
write.Alteryx(df_txt, 1)

I appreciate any assistance with debugging.

Thank you,

Chris

Hi @Archaeopteryx, you need to install the extra R packages in onder to get the PDF tool working. Follow these steps:

1. Go to C:\Program Files\Alteryx\R-3.4.4\bin (the version may differ)
2. Right click on the “R.exe” file and select “Run as administrator”
3. Enter the following commands

install.packages(“Rcpp”)
install.packages(“pdftools”)

You will be prompted to select a “cran mirror”, select any (though note some cran mirrors will not be able to provide the “pdftools” package and you may get an error message).

• Upon completion you should receive a message in the command prompt saying “package pdftools successfully unpacked and MD5 sums checked”. If you do not receive this message use stackoverflow or the Alteryx community to begin debugging.
• Run Alteryx and see if it works.
