4 years ago It should be able to accommodate a single treated unit (it could be bug though). Have you installed the most up-to-date version?
If yes, could you send us via email some sample data and code for us to replicate your error?

hello
I have some trouble with the gsynth function using r on OS
I want to analyse the economic growth effects of EU membership for Croatia. The SCM will pool from the neighbouring Balkan countries to conduct the analysis, none of which are EU members. Thus, this analysis apply a single case/unit treatment. However, after a lot of struggle I cannot seem to be able to do this with gsynth.
When I try to run gsynth I have my treatment variable (EU) and DV (growth) as well as some control variables, but the error I have been getting is this:
Error in rowSums(Y.ct) : 'x' must be an array of at least two dimensions
library(gsynth) Registered S3 method overwritten by 'GGally': method from +.gg ggplot2
system.time(m1 <- gsynth(gdpprcapitagrowth ~ eu + industry + agriculture + populationgrowth + uneployment + tradeinservices, data = qog, index = c("country", "year"), force = "two-way", EM = TRUE, CV = TRUE, r = c(0, 5), se = TRUE, na.rm = TRUE, inference = "parametric", nboots = 1000, parallel = FALSE))
Error in rowSums(Y.ct) : 'x' must be an array of at least two dimensions Timing stopped at: 0.055 0.009 0.078
I gathered that this was a problem with with my treatment and its lack of varying dimensions on it, so I tried adding another EU member state (that would receive the treatment) to the analysis, Bulgaria, and with this the gsynth function worked with no errors
My question is then the following: Is gsynth only possible for multiple with treatments with multiple units and not as in my case where only one unit receives treatment? Because this seems to be the case right now
Thank you and apologies for any potential misunderstandings of my question. I am quite new to github and to R
