Synth Problems, can´t install the package

[Pablo586]

Hello there, so I´m trying to use Syntetic Control for a project. But i have problems to download Synth Package, it tells me this:

install.packages("Synth")

(as ‘lib’ is unspecified)
also installing the dependency ‘optimx’

Error in install.packages : cannot open file 'C:/Users/Pablo Montero/OneDrive/Documentos/R/win-library/4.0/file3c8c33e01cb2/optimx/doc/Extend-optimx.pdf': Permission denied

Could you help me?

R has problems with cloud synced folders (OneDrive in this case), I would recommend setting your package library in a non synced folder. You can change the default library folder by setting your R_LIBS_SITE environmental variable on a .Reviron or .Rprofile file. For example:

# In a .Renviron file you can set it by adding a line like this one with the desired location 
R_LIBS_SITE="C:\\Program Files\\R\\R-4.1.1\\library"

For a more detailed explanation, you can read this blog post

Thank you very much. It helped me a lot.
Now I´m running the SCM and when I try to run the "dataprep" it tells me this:

"Error in dataprep(foo = basedata, predictors = c("pob", "emp", "hc", "rconna", :
unit.names.variable not found as character variable in foo."

You know why is that?? I have my panel data and everything but i don´t know why it keeps telling me that.

This is a different question, we like to keep things tidy around here so please ask it on a new topic providing a relevant reproducible example (reprex) illustrating your issue. Have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
