title: Error stargazer in R script multiple regression
body: <p>I am new to R and trying to make this script to work. I´m attempting to do multiple regression for <code>Y=dag, X1=OP, X2=NOKUSD</code> etc. with dummy-variables (a,b,c..). This is my script: </p>
  
  <pre><code>library(tokenizers)
  library(corpus)
  library(tidygraph)
  library(igraph)
  library(openxlsx)
  library(ggplot2)
  library(stringr) 
  data1 &lt;- read.xlsx("Kladding2.xlsx")
  head(data1)
  lm(dag~OP,data=data1) 
  library(stargazer)
  m4 &lt;- lm(dag~OP+NOKUSD+APR+OSEBX,data=data1)
  library(corrplot)
  stargazer(m4, title="data2", align=TRUE,
            no.space=TRUE,type="text") 
  m5 &lt;- lm(dag~OP+NOKUSD+APR+OSEBX+a+b+c+d+e+f+g+h+i+j+k+l+m+n+o+p+q+r+s+t+u+v+w+x+y+z+aa+ab+ac+ad+ae+af+ag+ah+ai+aj+ak+al+am+an+ao+ap,data=data1)
  stargazer(m5, title="data2", align=TRUE,
            no.space=TRUE,type="text") 
  
  </code></pre>
  
  <p>When I enter this script, the following error appears:</p>
  
  <pre><code>stargazer(m5, title="data2", align=TRUE,
  +           no.space=TRUE,type="text") 
  Error in stargazer(m5, title = "data2", align = TRUE, no.space = TRUE,  : 
    could not find function "stargazer"
  </code></pre>
  
  <p>I have already downloaded the package called stargazer.</p>
