I have a question about interpolating missing values in a dataframe. The dataframe is in the following, Column C has no data before 2009-01-05 and after 2009-12-31, how to interpolate data for the blanks? That is to say, interpolate linearly between these two gaps using 5.4 and 6.1? Thanks.
df time A B C 2009-01-01 3 4.5 2009-01-02 4 5 2009-01-03 3.3 6 2009-01-04 4.1 7 2009-01-05 4.4 6.2 5.4 ... 2009-11-20 5.1 5.5 6.1 2009-11-21 5.4 4 ... 2009-12-31 4.5 6 [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
