Solution :

As per your error wants to suggest that you may have the infinite or the missing values. Your log transformation can cause above error if the original data has really no missing values.

I am trying to explain you the solution with below code example:

> dbdata <- c(-1:3)
> l.dbdata <- log(dbdata)
Warning message:
In log(dbdata) : NaNs produced
> l.dbdata
[1]       NaN      -Inf 0.0000000 0.6931472 1.0986123
> dat.pca=prcomp(l.dbdata,center=TRUE,scale=TRUE)
Error in svd(x, nu = 0, nv = k) : infinite or missing values in 'x'
I hope above solution helped you in saving your time.
