error using krige function

Hi, i am new to rstudio, and i tried the krige function. But i always got text warning "There were 50 or more warnings (use warnings() to see the first 50)" after i run my krige function and keep getting my var1.pred and var1.var to NA. Can someone pls help me? Thanks

This is not a standard function in R. Therefore please declare the package.
Have you looked at the warnings ?
There is likely a problem with the data you provide to this function, but, we can't see that to judge it.

Please read this guide to understand how to share representative data.

hi, thanks for answering.
im sorry if my english and the format for sharing data is bad
i used this package :


I tried to do the kriging interpolation using the example data below. X and Y are the location coordinates. while Depth is the data that I have used to make kriging interpolation.

No X Y Depth
1 436162 9225207 72
2 421918 9228627 54
3 421796 9228805 66
4 425039 9226890 55
5 438778 9224380 60
6 428920 9219980 15
7 435402 9215807 72
8 444398 9218928 62
9 424909 9225120 55
10 430204 9225798 17

and the code is

koordinat <- read.csv("coba_koordinat432.csv")
coordinates(koordinat) = ~X+Y
x.range <- as.integer(range(koordinat@coords[,1]))
y.range <- as.integer(range(koordinat@coords[,2]))
grd <- expand.grid(x=seq(from=x.range[1], to=x.range[2], by=200),
y=seq(from=y.range[1], to=y.range[2], by=200))
coordinates(grd) <- ~ x+y
gridded(grd) <- TRUE
plot(grd, cex=1.5)
points(koordinat, pch=1, col='red', cex=1)
variogcloud<-variogram(Depth~1, locations=koordinat, data=koordinat, cloud=TRUE)
semivariog<-variogram(Depth~1, locations=koordinat, data=koordinat)
model.variog<-vgm(psill=600, model="Exp", nugget=80, range=8675)
fit.variog<-fit.variogram(semivariog, model.variog)
plot(semivariog, fit.variog)
krig<-krige(formula=Depth ~ 1, locations=koordinat, newdata=grd, model=model.variog)

and after i run the code above, i got warning massage like this,

Warning messages:
1: In flat_str(content, breaks) : Coercing content to character
2: c(421779, 421979, 422179, 422379, 422579, 422779, 422979,....,etc
