Question: I am new to R and I need help. I have created correlation matrix using the rcorr command. I would like to see this as a table so I can export it and email to my prof. The problem I am running into is this error message. I am at my wits end on how to fix it. I have tried data.frame command as well as write.table command. 

Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors = stringsAsFactors) : 
 cannot coerce class ""rcorr"" to a data.frame

Answer: 
You might just look at the structure of the rcorr object. Ill create one with:

```
> rcx=rcorr(x)

```

then look at its stucture with:

```
> str(rcx)
List of 3
 $ r: num [1:10, 1:10] 1 0.0503 0.0309 0.0462 0.0719 ...
  ..- attr(*, "dimnames")=List of 2
  .. ..$ : NULL
  .. ..$ : NULL
 $ n: int [1:10, 1:10] 100 100 100 100 100 100 100 100 100 100 ...
  ..- attr(*, "dimnames")=List of 2
  .. ..$ : NULL
  .. ..$ : NULL
 $ P: num [1:10, 1:10] NA 0.619 0.76 0.648 0.477 ...
  ..- attr(*, "dimnames")=List of 2
  .. ..$ : NULL
  .. ..$ : NULL
 - attr(*, "class")= chr "rcorr"

```

So it is an object with 3 components, the first and last one can be made into sensible tables. I am not sure which one of these you want to print.

If you need them to be dataframes this will work

```
 df.rcx.r=data.frame(rcx$r)

```

or 

```
 df.rcx.p=data.frame(rcx$P)

```

Then you can save these to a csv file with:

```
 write.csv(df.rcx.r,'correlationmatrix.csv')

```
Use this code: `df.rcx.p = as.data.frame(rcx$P)`

The code `as.data.frame` coerces that table into a dataframe. 
Then when you save the file into a csv, just open it with Excel then you can save either as csv or Excel.
