Editing a Row Value in R

I have a data frame that looks like this

Pick   Name     Team Round           Player Position Position..
1    1   Javi   Texans     1 Patrick Mahomes        QB        QB1
2    2 Justin   Chiefs     1  Russell Wilson        QB        QB2
3    3  Blake   Titans     1   Lamar Jackson        QB        QB3
4    4 Connor Dolphins     1   Deshaun Watson       QB        QB4
5    5  Isaac  Jaguars     1     Carson Wentz       QB        QB5
6    6   Fitz     Rams     1     Dak Prescott       QB        QB6

with more rows of course and some of the rows in the Player, Position and Position... Column are empty because they haven't been drafted yet. Is there a way to just manually insert the names, pos, pos... of the newly drafted players.

I tried 

Redraft[112, "Player"] <- "Calvin Ridley"; Redraft

Since the empty cells start on row 112, but it just came up as N/A

When I do that I also get an error message:

Warning message:
In `[<-.factor`(`*tmp*`, iseq, value = "Calvin Ridley") :
  invalid factor level, NA generated

and the data frame looks like

08  108    Jack    Packers     4   TE3       Darren Waller       TE
109  109  Justin     Saints     4   LT6        Taylor Lewan       LT
110  110     Sam   Steelers     4   FS5         Kevin Byard       FS
111  111  Jeremy    Falcons     4   LB7      Isaiah Simmons       LB
112  112    Will      Bills     4     1                <NA>         
113  113  Jeremy      Colts     4     1

And heres the whole data frame: 

structure(list(Pick = 1:384, Name = structure(c(12L, 14L, 1L,

jay.sf's answer is correct, of course, but I'd add my 2¢ since I think it's missing the point.

The reason you have factors instead of plain strings here in the first place, is kind of a historical accident with R being a statistical language. In practice, you rarely want to be dealing with factors in a dataframe of this kind. You probably want your player names to be plain-old strings.

Typically when you read a dataframe from a file, e.g. via read.csv, you have the option to pass the argument stringsAsFactors = TRUE, to ensure that strings are kept as strings rather than converted to factors. Some people (e.g. this guy) feel so strongly against this bizzare default behaviour, that they include a line in their .Rprofile to make importing data with stringsAsFactors=T as their default. (but this is dangerous for writing code that works the same across users with different .Rprofile initializations!)

If you already have the dataset, you can convert your factors to strings instead:

df[ , 'Player'] <- as.character( df[ , 'Player' ] )

You can now continue with your analysis without worrying about factors and their annoyances.

E.g. setting a new name is as simple as you'd expect:

df[112,'Player'] <- 'Calvin Ridley'

You're dealing with a factor column. "Calvin Ridley" isn't yet a level of the factor. After adding it you can rename the cell.

class(Redraft$Player)
# [1] "factor"

levels(Redraft$Player) <- c(levels(Redraft$Player), "Calvin Ridley")
Redraft[112, "Player"] <- "Calvin Ridley"
Redraft[112, "Player"]
# [1] Calvin Ridley
# 112 Levels:  A.J. Brown Aaron Donald Aaron Rodgers Adoree' Jackson Allen Robinson ... Calvin Ridley
