Dear Studio community, I am here to ask you some help about anova test on lmer model.
Here the script:
data_m<-read.delim("exp5_30d_ok.txt")
summary(data_m)
data_m$trattamento<-ordered(data_m$trattamento, levels=c("FM","DM"))
model_Yield<-lmer(Yield ~ trattamento*time + (1|id_sample), data=data_m)
anova(model_Yield)
[...]
console output after anova(model_Yield):
Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd'
The error started to appear after editing the dataset: I removed data referred to one sample (that was an outlier) keeping everything just as it was. I do not know what's happening because I tried again with the first dataset (with the outlier) and it works, without that sample it doesn't.
If you need eventually some more infos about the dataset just let me know here or send me a message.
Thanks in advance for your availability,
Best Regards
Christian
