title: Excel matrix to R matrix for bipartite network analysis: conversion issue
body: <p>I am new/inept using R. I have bipartite pollinator network data in a matrix format in excel- superficially similar to the Safariland dataset but unlike Safariland data I am unable to perform functions such as "networklevel" or "visweb".</p>
  
  <p>I have tried multiple ways to include column 1 as row headers but do not fully understand why I cannot do so. My data appears to be a table dataframe. </p>
  
  <p>I have tried </p>
  
  <pre><code>as.matrix(MYDATA, row.names.data.frame(1)
  head(MYDATA, Inf)
  data.matrix(MYDATA, rownames.force= NA)
  read.table(file= MYDATA, row.names= 1)
  </code></pre>
  
  <p>To make my data into a suitable matrix for analysis in the bipartite package.</p>
  
  <p>Any advice? <a href="https://i.stack.imgur.com/aOXOj.jpg" rel="nofollow noreferrer">Image: Imported CSV file</a></p>
