Then show your code so we can focus on what you haven't yet figured out. Have
you read the examples in the merge help page?

Yes I'm reading that presently
The closest I've gotten has been
df3 <- merge(df1, df2, all = TRUE)

You can also
Have you looked at the merge function in base R?

Hi
Keep posts also to r-help, others could give you different/better solutions.
Regarding ordering, see ?order or ?sort. However this is mainly necessary only
for plotting or exporting data.

Hi Drake,
Petr's suggestion to use the merge() function is good.
Another (possibly overkill) approach is to use functions from the dplyr
package, which is a fantastic package to get familiar with.
For example, the last alternative that Petr suggests is an example of what
is called a "left join"
Hi
I wonder why such combination is so complicated in your text book.
Having data frames fr1 and fr2
> dput(fr1)
structure(list(Fruit = structure(c(1L, 3L, 2L), .Label = c("banana",
"mango", "pear"), class = "factor"), Calories = c(100L, 100L,
200L)), class = "data.frame", row.names = c("1",
The whole thing is a merge operation, i.e.
> FruitNutr <- read.table(text="
+ Fruit Calories
+ 1 banana 100
+ 2 pear 100
+ 3 mango 200
+ ")
> FruitData <- read.table(text="
+ Fruit Color Shape Juice
+ 1 apple red round 1
+ 2 banana yellow oblong 0
+ 3 pear green pear 0.5
+ 4 orange orange round

Hello everyone,
I'm working through this book, *Humanities Data in R* (Arnold & Tilton),
and I'm just having trouble understanding this maneuver.
In sum, I'm trying to combine data in two different data.frames.
