I want to perform IDW interpolation using R using the idw command from the gstat package. I have this data:

A tibble: 40 × 7

Fecha Dispositivo Id x y Altura Tmin

1 2024-05-15 J72893 72893 246734 6223612 282 0.23
2 2024-05-15 J72506 72506 247291 6226657 247 -3.52
3 2024-05-15 J71625 71625 245754 6226497 288 1.7

the code is:

your textlibrary(pacman)
your textp_load(sf,raster, rgeos, wesanderson, sp, mapview, gsstat, tidyverse, readx1)
your textmapview()
your textfnc <- shapefile(‘C:UsersponceOneDriveEscritorioSan+VicenteSan Vicente.shx’) `#is the area of ​​interest

your textext <- extent(fnc)
your textgrd <- expand.grid(x <- seq(from = ext[1], to =ext[2], by = 10),
y <- seq(from = ext[3], to =ext[4], by = 10))
your textnames(grd) <- c(“x”, “y”)
your textcoordinates(grd) <- c(“x”, “y”)
your textgridded(grd) <- TRUE
your textcrs(grd) <- crs(fnc)

your textinfo <- read_excel(“C:/Users/ponce/OneDrive/Escritorio/info.xlsx”)
your textpts <- info
your textcoordinates(pts) <- ~ x + y
your textcrs(pts) <- crs(fnc)

your textidw.p <- gstat::idw(Tmin ~ 1, pts, newdata = intento, idp=2)

but give me:
Data summary:

var1.pred var1.var
Min. :-2.068 Min. : NA
1st Qu.:-2.068 1st Qu.: NA
Median :-2.068 Median : NA
Mean :-2.068 Mean :NaN
3rd Qu.:-2.068 3rd Qu.: NA
Max. :-2.068 Max. : NA
NA’s :49952

If I made the grill in another way. The error remains, as I put below:

your textGrid <- as.data.frame(spsample(pts, “regular”, n =50000))
your textnames(Grid) <- c(“x”,”y”)
your textcoordinates(Grid) <- c(“x”,”y”)
your textgridded(Grid) <- TRUE
your textfullgrid(Grid) <- TRUE
your textproj4string(pts) <- proj4string(pts)
your textproj4string(Grid) <- proj4string(pts)
