QUESTION
I am using the isomap-function from vegan package in R to analyse community data of epiphytic mosses and lichens. I started analysing the data using NMDS but due to the structure of the data ran into problems which is why I switched to ISOMAP which works perfectly well and returns very nice results. So far so good... However, the output of the function does not support plotting of species within the ISOMAP plot as species scores are not available. Anyway, I would really like to add species information to enhance the interpretability of the output.
Does anyone of you has a solution or hint to this problem? Is there a way to add species kind of post hoc to the plot as it can be done with environmental data?
I would greatly appreciate any help on this topic!
Thank you and best regards, Inga

QUESTION
I'm trying to replace NA values from one matrix with values from a row with the same name in a separate matrix.
This is part of a loop to process 32 matrices with differing row numbers so I need code that references the locations of the NA's, preferably by row name. The maximum number of rows is 7, all data has two columns.

QUESTION
I'm doing an analysis of scientific publications from around 30,000 journals. My list has over 1.3 million records but with several duplicates (ex: a paper with more than one author from different institutions appear more than once).
Well, I would like to perform a record comparison that would result in a new ID column with the same value for the same papers. This would be very easy with dplyr if the records were equal, but there are several matching problems, as different authors may include the information in distinct ways, or they can make mistakes.
Here is an example of the type of records and problems I have, and the type of ID I would like to generate:
...ANSWER
Answered 2021-Feb-19 at 20:11This seems to be something that studied by Record Linkage literature. A R
package to use might be fastlink
here.
In general, Record Linkage tries to solve the problem that there are two datasets: A
and B
, where you know that some of the A
records must be matched with entries from B
, but there isn't a perfect identifier to tell you so. Hence we need to leverage different columns of information to help us determine what is a match or not.
I notice that some comments suggesting soundex
or ISSN
, which are very useful observations, but Record Linkage methodology leverages all those information (and even more) to make the match. I believe this is something you are after.
PS: doi
should be unique identifier for journal articles and ISSN
should be identifier for journals. But some journals have both print
and online
ISSN, so there may be cases where two articles come from the same journal but have different ISSN
s.
PS2: What would make the comparison more effective is what they called "blocking". If you take articles from same journal and same publication year, and consider them as smaller groups, then you compare articles within each group. Here you are saving lots of time and resources since you are not matching between articles that are obvious not-matches.

I am trying to apply an ifelse statement to all the cells in my data frame. I'm pretty sure I am overthinking this but would appreciate some help/guidance!
I have a dataframe of (slightly modified) percent cover of vegetation from a number of sites where the site names and the vegetation types are the row names and column names, respectively (ie. the data frame should only consist of numeric values):
...ANSWER
Answered 2020-Mar-23 at 21:51You mentioned ifelse
, I think it's straight-forward enough to apply this to each column using lapply
. (I'll add the isnum
check in case there are non-numeric columns in the data, feel free to ignore it if your data is always numeric
.)
