accessing a data frame with row names
Readers,
I have entered a file into r:
,column1,column2
row1,0.1,0.2
row2,0.3,0.4
using the command:
dataframe<-read.table("/path/to/file.csv",header=T,row.names=1)
When I try the command:
dataframe[,2]
I receive the response:
NULL
I was expecting:
row1 0.2
row2 0.4
What is my error with the syntax please?
Yours,

number of pairwise present data in matrix with missings
is there a smart way of determining the number of pairwise present data
in a data matrix with missings (maybe as a by-product of some
statistical function?)
so far, i used several loops like:
for (column1 in 1:99) {
for (column2 in 2:100) {
for (row in 1:500) {
if (!is.na(matrix[row,column1]) & !is.na(matrix[row,column2])) {
pairs[col1,col2] <- pairs[col1,col2]+1

Function to read a string as the variables as opposed to taking the string name as the variable
I am writing a custom function that uses an R-function from the
reshape package: cast. However, my question could be applicable to
any R function.
Normally one writes the arguments directly into a function, e.g.:
result=cast(table1, column1 + column2 + column3 ~ column4,
mean) (1)
I need to be able to write this statement as follows:
result=cast(table1, string_with_columns ~

Question: coding protected methods
Apologies first, because I need to ramp up on Ruby and coding Ruby in Rails,
however it''s my 3rd day with this beast :) so I''m asking :
When I added protected methods to the model before it was like:
protected
method....................
end
Would this be a valid way to write a protected method as well ?:
attr_protected :column1, :column2

R Shiny Help - Trouble passing user input columns to emmeans after ANOVA analysis

I have experience coding with R, but am brand new to R Shiny. I am trying

graphs that will allow users to view their results. However, I am getting

Help with syntax error
Hi,
I have written boxplot commands of this form before, but I don''t quite understand why the function call is reporting a syntax error in this instance. All parameters passed to the function are strings.

Cores hang when calling mcapply
Hi Gregg.
Just wanted to follow up on the solution you proposed.
I had to make some adjustments to get exactly what I wanted, but it works, and takes about 15 minutes on our server configuration:
temp <-
??????open_dataset(
????????????sources = input_files,
????????????format = 'csv',
????????????unify_schema = TRUE,
????????????col_types = schema(

Cores hang when calling mcapply
Hello Thomas,
Consider that the primary bottleneck may be tied to memory usage and the complexity of pivoting extremely large datasets into wide formats with tens of thousands of unique values per column. Extremely large expansions of columns inherently stress both memory and CPU, and splitting into 110k separate data frames before pivoting and combining them again is likely causing resource

Reading sections of data files based on pattern matching
I am about to write general functions to read the output of simulations
models.
These model generate output files with different sections which I want
to analyze plot etc.
Since this will be used many people at the department I wanted to make
sure that will do this in the best way.
For instance I want to read a snippets of data from a text that look
like this.

Cores hang when calling mcapply
How is the server configured to handle memory distribution for individual users. I see it has over 700GB of total system memory, but how much can be assigned it each individual user?
AAgain - just curious, and wondering how much memory was assigned to your instance when you were running R.
regards,

Cores hang when calling mcapply
Hi Thomas,
Glad to hear the suggestion helped, and that switching to a `data.table` approach reduced the processing time and memory overhead?15 minutes for one of the smaller datasets is certainly better! Sounds like the adjustments you devised, especially keeping the multicore approach for `make_clean_names()` and ensuring that `ID_Key` values remain intact, were the missing components you
