getSymbols(c("PI","RSXFS", "TB3MS", src="FRED",from="1959-1-1", from="1992-1", from="1934-1-1")
How can I load data by using getSymbols for different start dates for multiple variables?
I needs 200 variables from FRED. I can download the FRED CODE easily, but the problem is that dates. Each variables have different starting date. First I load data set with time series format and then i will use window commend for fixing the same time period for all 200 data.
