Re: [R] comparition of occurrence of multiple variables between two dataframes
Hi Instead of posting head(data100) try to copy output of dput(head(data100)) directly to your post. This can show us your exact data together with their modes. And switch to plain text emails, HTML formating results in quite messy mails.

Re: [R] comparition of occurrence of multiple variables between two dataframes
You need to learn how to send plain text messages. See below what happened to your html table when the list converted it to plain text. It is unreadable. In your original post, you say "The very last column is the value given to the tree, according to the structures found on it (each structure giving a number of point to the tree by its presence on it)." That suggests that the point value is based on the structures. If that is so the answer to your question is "yes", higher point values will have different numbers/combinations of structures because you computed point value from the structures. No statistical test between the two groups will be valid because the groups were not formed independently of the structures. Looking for associations between different types of structures would be a different question that would not be based on point value at all but would use some measure of association/correlation.

But if you are after simple difference you may use compare package ( https://cran.r-project.org/web/packages/compare/index.html). Best, -m PS: Data is already plural :) datas does not exist.

Re: [R] comparition of occurrence of multiple variables between two dataframes
Do you have a simplified example with a code? It is not clear to me what do you mean by tree but if you refer to tree data structure, maybe you could change the data structure to tree (https://cran.r-project.org/web/packages/data.tree/vignettes/data.tree.html) and try to write comparison of two tree objects. It might be easier that data.frame alone.

[R] comparition of occurrence of multiple variables between two dataframes
Hi everyone, I need your help to solve a problem with occurrence and two dataframes. I have an excel table of 15200 lines. Each line correspond to a tree analyzed for its structures. I have all the structures in columns (48 structures). The occurrence of these structures has been counted on every tree. For example, the tree 12607 has 3 structures CV11, 1 structure IN12 and none (0) of the rest of all the other structures. The very last column is the value given to the tree, according to the structures found on it (each structure giving a number of point to the tree by its presence on it). The question is: Are there some structures, or combination of structures, which give a high value to the tree ? Of course, according to the value of each structure, we can see which one has a higher value than the others (ex: structure CV11 has a value of 15, structure IN12 has a value of 4). But what I want to know is, if we take all the trees having a final value higher than 100 (we create a new dataframe "data100"), and we compare with the trees having a final value under 100 (we create another dataframe "data0"), can we find a significant difference in the number and occurrence of structures found on these trees? And which structure is related to trees with a higher value than 100 ? For now, I have only a visual answer to the question. I did two boxplot of the data100 and data0, and I have seen some différences : 2 structures are only found in the data100, which can be caracteristic of a final value higher than 100. The problem is that I’m looking for a test to prove this. If you have any idea or proposition for solving this problem.. it will be great! Best wishes, C.
