How can I read the specified column in the generated data frame in R?
<p>Here is my code:</p>

<pre><code>x&lt;-c(1300,541,441,35,278,167,276,159,126,60.8,160,5000,718,9740,135,3480,264.6,379,170,251.3,155.84,187.01,850)
y&lt;-log10(x)
# load fitdistrplus package for using fitdist function
library(fitdistrplus)
# fit logistic distribution using MLE method
x.logis &lt;- fitdist(y, "logis", method="mle")
b1 &lt;- bootdist(x.logis, bootmethod="param", niter=20)
b1# Here are 20 b1.
</code></pre>

<p>How can i read the parameter values (location) in b1 ? Thank you very much !</p>
