synth() and fn.V():
quadopt = "LowRankQP" no longer falls through to
undefined-variable code. The deprecation message is now raised via
stop() rather than cat(), which matches the
user’s expectation that the function fails fast on an unsupported
option.
dataprep(): the missing-data warning loop in the X0
(control predictors) section now iterates over nrow(X0)
instead of nrow(X1). Previously it covered only the first
length(time.predictors.prior) rows, missing roughly
(n_controls - 1) / n_controls of the cells.
synth(): the error message for
ncol(Z0) < 2 no longer mentions “specify only one
treated unit” (it is checking for at least two control units).
path.plot(): Ylim is now padded by a
fraction of the data range, not by 0.3 * Y.min. The old
formula gave 0.7 * Y.min for negative Y.min,
which moved the lower bound toward zero and cropped the bottom
of negative-valued series.
synth(): messages such as “X1, X0, Z1, Z0 all come
directly from dataprep object”, “searching for synthetic control unit”,
and the final summary block printing MSPE (LOSS V) and the
solution vectors are now gated by verbose = TRUE. With the
default verbose = FALSE, synth() runs
silently. Set verbose = TRUE to restore the previous
chatter.synth.R.is.vector(X0.scaled) defensive
branch in synth.R (ncol(X0) < 2 errors out
earlier)."\ Please..." →

unsupported-quadopt branch (also clarifies error
messages).These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
