Hi David,
I found this blog post helpful. I had a similar situation where I was
installing R 3.3 on CentOS 6, and I found these instructinos worked well:

The only problem I had is that the instructions as written do not allow for
using the R installation wit
Hi
The problem with rda() and getting some result like:
Regularization parameters:
> NULL
may be related to the package �agricolae� as when I load it, rda() fails to
produce a plot. To solve, quit R and re-start it. This time, do not load
�agricolae�.

Hello,
I am wondering if I can re-subscribe to the R Programming course on
Coursera at a later point in time and pick up where I left off.
I completed everything except for one assignment in Week 3 which required
peer review of the assignment for a grade.
Thanks!

Dear R helpers,

Perhaps it is worth pointing out (in case the OP thinks this is SQL) that the
special value NA is used for "missing" in R.
y[1] <- NA
works just fine.

You are attempting to assign NULL, which is a zero length special ob

If you are referring to assignment in the evaluation environment

Thanks, I didn't know the email function before.
The code works. I found that using "=" is different from using "<-".

Thanks for your reply. I created the two dataframes (just numbers from txt
files) in one for loop, so that it is confused to give them the same column
names. That is the reason that I give them different column names to
differentiate them, but it causes difficulty in later combining them.

Hi Lily,
maybe you should read up on what bind_rows/bind_cols (or the base functions
rbind and cbind) do.
bind_cols and cbind will fail in this case because of the different number
of rows.
bind_rows and rbind will fail because the column names are different - how
can R know that month and mon r
Is there a reason not to just rename the columns?
First, you should use dput(DF1) and dput(DF2) to send your example tables to
the list:
DF1 <- structure(list(year = c(1981L, 1981L, 1981L, 1981L), month = c(1L,
1L, 1L, 1L), day = 1:4, product1 = c(18L, 19L, 16L, 19L), product2 = c(56L,
45L, 48
Hi all,
I have a question about combining two data frames. For example, there are
the two dataframes below, with the same structure but different column
names and column lengths. How to add the values in DF2 to the end of DF1,
though the column names do not match? How to add more than two? Thanks.
You may run into memory issues if the table is that large in which case you may
need to break your customers into subsets and process each subset separately.
Then combine the results of the subsets into a single file.
There are a couple of relatively easy ways to speed things up, but I don't kn

Dear Greg,
Make sure that your x variable (Betas) is categorical. That is required for
geom_boxplot().
And please do read the posting guide.
