Description
I have a model that I run from CmdStan:
./mymodel optimize data file=tmp.r output file=output.csv
And then in R:
opt = read_stan_csv("output.csv")
Gives:
Error in all_int_eq(warmup) : not all are integers
In addition: Warning message:
In FUN(X[[1L]], ...) : line with "Elapsed Time" not found

Research direction
Start at the read_stan_csv() entry point and reproduce the issue with the shown CmdStan optimize command and output.csv. Inspect how optimize output is handled around the missing "Elapsed Time" line and warmup parsing. Done means read_stan_csv("output.csv") can parse this output without the reported error or warning.
