I have a set of data in ranges like:



 x|y|z
-4|1|45
-4|2|68
-4|3|96
-2|1|56
-2|2|65
-2|3|89
0|1|45
0|2|56
0|3|75
2|1|23
2|2|56
2|3|75
4|1|42
4|2|65
4|3|78


Here I need to interpolate between x and y using the z value.



I tried interpolating separately for x and y using z value by using the below code:



interpol<-approx(x,z,method="linear")
interpol_1<-approx(y,z,method="linear")


Now I'm trying to use all the three columns but values are coming wrong.

  • I need to interpolate x,y and z. say there is a missing value for x,y,z for 1st and 2nd row. We need to find this intermediate missing value for x,y,z column.

In your script you forgot to direct to your data.frame. Note the use of $ in the approx function.



interpol <- approx(df$x,df$z,method="linear")
interpol_1 <- approx(df$y,df$z,method="linear")


Data:



df <- data.frame(
x = c(-4, -4, -4, -2, -2, -2, 0, 0, 0, 2, 2, 2, 4, 4, 4),
y = c(1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3),
z = c(45, 68, 96, 56, 65, 89, 45, 56, 75, 23, 56, 75, 42, 65, 78)
