Dear R community In my experiment, there are three treatments (F, R, and S), and the storge temperatures of these seeds were 4, 10 and 15. The seeds number of the treatment were the same. The question is whether the treatments and storage temperatures changed the seed germinating. The data attached as a ".csv" file names "g.csv".
The mail server checks to see what file type is attached. If it is not mime-text, it gets discarded, and I suspect that your mail client sent it as something else. You might get better success with a vanilla editor like Notepad on Windows or TextEdit.app on a Mac and make sure to save with extension ".txt". If you want everyone to "be on the same page" you should also include your code.
I performed a generalized linear mixed model using glm. Time and Temp are significant (p < 0.0001) and I would like to perform post- hoc comparisons to check where the difference among Time and temp categories but I did not find a solution in R help list or others.
You might want to look at ?p.adjust to see if it will meet your post- hoc testing needs. If not you can also look at the multcomp package.
Thank you very much in advance for your help. -- Xishuangbanna Tropical Botanical Garden Chinese Academy of Sciences Menglun Town, Mengla County Yunnan 666303 Tel.: +86-691-8716759
