prepare_data function error #5

Closed htrou closed 4 years ago

htrou commented 4 years ago

I attempted to use the prepare_data function on my data and get the following error

Error in interp.old(x, y, z, xo, yo, ncp = 0, extrap = FALSE, duplicate = duplicate,  : 
  all data collinear
In addition: Warning messages:
1: In prepare_data(dat) : NAs introduced by coercion
2: In prepare_data(dat) : NAs introduced by coercion

Now I'm a little confused, as I have another dataset from a different day that works perfectly fine. The two datasets are identical, except of course for dates and concentrations. As far as I can see, there's no good reason for this error. I have attached the two datasets. SM1020.csv is the one that is working fine, SM1021.csv is the one that is not. Thank you in advance for any advice you can offer.

Best regards, Haydn SM1020-21.zip

I found out the issue. The time needs to be in hh:mm, not hh:mm:ss. SM1021 had the latter. It's a little annoying, since I have 8 weeks of data that I'll need to change the time format for, but I'm just glad it's working
