I now will add a column of values to the table using the argument add_columns(ame(c('x','','x','','',''))) = '), estimate = 'estimate', fmt = fmt_statistic(p.value = fmt_sprintf('%.2e'))) Tab <- modelsummary(list('HP' = reg1, 'WT' = reg2, 'GEAR' = reg3),stars = TRUE, statistic = c('s.e. I plot the summary of the two regressions in a table such as the following: Reg3 <- feols(gear ~ vs + am + qsec | carb, data = mtcars) Reg2 <- feols(wt ~ vs + am + qsec | carb, data = mtcars) Reg1 <- feols(hp ~ vs + am + qsec | carb, data = mtcars) Note that the first command mutating the gender column nhanesAnalysis is in tidyverse format using the pipe, while the last command is in base R format.Suppose I have a table summarizing regressions using the modelsummary package such as the following: library(fixest)

RENAME COLUMN IN R 64 BIT

A 64 bit version of R can be downloaded from info at or Using 64 bit may be extremely beneficial for very large dataset.

RENAME COLUMN IN R 32 BIT

Machine$integer.max (starts with a dot.) For a 32 bit computer this will be exactly 2147483647. To know the larger Integer that R can hold can be revealed by command. “We can use the L suffix to qualify any number with the intent of making it an explicit integer.”įinally, internally this is related also to the amount of memory (RAM) used by the computer to hold an integer and that may depend if it is a 32 bit or a 64 bit system. But perhaps the simplest approach is to qualify our constant with the suffix character L.” We can do this by calling the function as.integer or using various other techniques.

There are, however, times when we would like to explicitly create an integer value for a constant. In most cases, the difference between an integer and a numeric value will be unimportant as R will do the right thing when using the numbers. “Perhaps unexpectedly, the number returned from the expression 1 is a numeric.

What’s the difference between 1L and 1?Īlso in the R Language Definition book ( R Core Team ( 2020b)) 37, 38 it is stated, in reference to the number 1 (as in: class(c(1))).

The author of this in R never explained why he chose the notation, but it is shorter than as.integer(10), and more efficient as the coercion is done at parse time. There are multiple entries in Stack Overflow for this, including: Primary sampling unit (PSU) masking and variance estimation in complex surveys available online 36. NHANES data uses the method described in article

The only data specification is for INDFMPIR others can be found on the DEMO_I web page and listed below: Chosen columns and their description Code Only columns that will be selected in the next step are altered. However, this could also have been done with Tidyverse method by using the rename() function as we have seen in section 10.6. It is performed with base R subsetting with $ and overwriting the specified column. This code portion has a goal to make the data easier for humans to understand by changing the name of the data columns.
