Thank you Jeff. I think the code you wrote works. The value I put in the
output was just guessing by looking at the graph.
Thank you once again Jeff.
temp<-structure(list(X = c(1468285.96, 1468476.96, 1468479.96, 1468482.96,
1468485.96, 1468467.96, 1468470.96, 1468473.96, 1468476.96, 1468479.96,

Piecewise linear interpolation is implemented in the ?approx function. It does
not agree exactly with your Output, I don't know if there is something else you
are accounting for it if your Output is in error.
temp$index <- approx( table2$temp, table2$Index, temp$temp )$y
BTW your code was usabl
Hi R Users,
I have two tables, one is temperature data (temp) and another table is a

temperature data (temp) based on Table 2 (or graph, which is a suitability
curve), but I could not figure it out.
Are there any suggestions f
