error message :Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :NA/NaN/Inf dans 'x' .

Good morning everyone,
i wrote this code adf.test(log(z1)) but it dosen't work since an error message:
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : NA/NaN/Inf dans 'x' .
What shall I do please ?

Do you know the values of x?
are they NA, NaN, or Inf?

What policy would you like to use given that some of your data is absent?
Remove.. impute...?

thank you ! the problem is resolved .

hello,
they are numbers : NA

the data that i used are imported from excel . and i did not remove them .
this is the code that i wrote
##testing the stationnarity of google trend ##
summary(gt_4cc)
x1 <- gt_4cc$BTC adjusted Gt
y1 <- gt_4cc$LTC adjusted Gt
z1 <- gt_4cc$ETH_C adjusted Gt
w1 <- gt_4cc$ETH adjusted Gt

##log##
adf.test(log(x1))
adf.test(log(y1))
adf.test(log(z1))
adf.test(log(w1))

the adf test dosen't work only with y1 and z1
