R help - Mar 2013 - Working with string

Hello again,

Let say I have following string:

Vec <- c("sada", "asdsa", "sa")

Now I want to make each element of this vector with equal length.
Basically I want following vector:

c("sada ", "asdsa", "sa   ")

Therefore we can get:
> nchar(c("sada ", "asdsa", "sa   "))
[1] 5 5 5


Is there any possiblity that we can do it programetically? Because I
need to handle a really big vector.

Thanks for your help.

?nchar  will tell you how many characters are in each string (mod multibyte
locales)

and you can use this to extend any that are shorter than the max with
blanks or whatever.

Hello again,

Let say I have following string:

Vec <- c("sada", "asdsa", "sa")

Now I want to make each element of this vector with equal length.
Basically I want following vector:

c("sada ", "asdsa", "sa?  ")

Therefore we can get:
> nchar(c("sada ", "asdsa", "sa?  "))
[1] 5 5 5


Is there any possiblity that we can do it programetically? Because I
need to handle a really big vector.

Thanks for your help.

?format will by default, left justify and pad with spaces to the longest length
element in the character vector:

Vec <- c("sada", "asdsa", "sa")
> format(Vec)
[1] "sada " "asdsa" "sa   "
