Readers, Am trying to use the function 'approx' to interpolate time series data sets:
data1: 01:23:40 5 01:23:45 10 01:23:50 12 01:23:55 7 data2: 01:23:42 01:23:47 01:23:51 01:23:54 The objective is to obtain interpolated values of 'data1' column 2 (5, 10, 12, 7) for the times shown in data2. Tried the following command but received the error shown: data3<-approx(data1,xout=data2) Error in approx(data1, xout = data2) : (list) object cannot be coerced to type 'double' What is my mistake please? -- r2151 ______________________________________________ R-help@r-project.org mailing list 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.
