How to save summary(lm) to a file?
I think one option could be sink()
which will output the results to a text file rather than the console. In the absence of your dataset I've used cars
for an example:
sink("lm.txt")
print(summary(lm(cars$speed ~ cars$dist)))
sink() # returns output to the console
lm.txt
now looks like this:
Call:
lm(formula = cars$speed ~ cars$dist)
Residuals:
Min 1Q Median 3Q Max
-7.5293 -2.1550 0.3615 2.4377 6.4179
Coefficients:

@Roland 's suggestion of knitr
is a bit more involved, but could be worth it because you can knit input, text output, and figures in to one report or html file easily.
How to save multiple summary(lm) to a file/files?
I don't know enough about R's internals to say why you need to do this, but if you wrap the summary
call with a call to print
your code works:
output_folder<-c("C:/temp/")
for(counter in 1:3){ #for loop it saves empty files
#counter<-2
x<-rnorm(100,0,1)
y<-rnorm(100,0,2)
lm.model<-lm(x~y)
sink(file=paste(output_folder, "RegressionSummary_", counter,".txt", sep = ""))
print(summary(lm.model))
sink()
}
How can I save my multiple lm summary output to a data frame or csv?
Sorry I wrongly closed this as a dupe at the beginning. Thanks to my friend for reopening it.
For "mlm"
model class this is very efficient.
First, you need to Fitting a linear model with multiple LHS
Then let fit
be your fitted model object (of "mlm"
and "lm"
class), extract its coefficients by
beta <- coef(summary(fit))
This is a list of coefficient tables.
Then, let's collapse it into a data frame:
tab <- do.call(rbind.data.frame, beta)
Now you just write this data frame into a "csv" file as usual.
As a quick test, you can use the toy dataset provided in the linked thread.
Write Regression summary to the csv file in R
Provided your data set and your comments, I would do something like
abc <- read.table(text = "
Order.Week..BV. Product.Number Quantity Net.ASP Net.Price
1 2013-W44 ABCDEF 92 823.66 749
2 2013-W44 ABCDEF 24 898.89 749
3 2013-W44 ABCDEF 243 892.00 749
4 2013-W45 ABCDEF 88 796.84 699
5 2013-W45 ABCDEF 18 744.80 699", header = T) # Yor data
fit <- lm(Net.Price ~ Quantity + Net.ASP, data = abc)
x <- cbind(abc, t(as.numeric(coefficients(fit))), t(as.numeric(summary(fit)$coefficients[, 4])), summary(fit)$r.squared)
names(x)[(length(x) - 6):length(x)] <- c(paste("coeff", names(coefficients(fit))), paste("P-value", names(summary(fit)$coefficients[, 4])), "R-squared")
Which will return
Order.Week..BV. Product.Number Quantity Net.ASP Net.Price coeff (Intercept) coeff Quantity coeff Net.ASP P-value (Intercept) P-value Quantity

Is there a way to export the linear regression summaries from R as an image? I need to export the summaries as .jpeg or as .png
The package "Stargazer" would let you export the summary into beautifully formatted html, LaTex or plain ASCII text.
Just open the resulting html file in a browser, copy it as is or capture it as an image and paste it into your presentation.
library(stargazer)
data <- as.data.frame(cbind(a = rnorm(30), b = rnorm(30)))
fit_lm <- lm(data, formula = a ~ b)
stargazer(fit_lm, type = "html", out = "fit_lm.html")
PNG with the lm summary
Save the result from summary(lm) to use in PowerBi
Try something like this:
fit <- lm(hwy ~ displ, data = mpg)
txt = capture.output(print(summary(fit)))
plot(NULL,xlim=c(-1,1),ylim=c(-1,1),xaxt="n",yaxt="n",bty="n",xlab="",ylab="")
text(x=0,y=0,paste(txt,collapse="\n"))
You might need to look at using stringr::str_pad to make the text prettier.. but this should get you something that works.
This is how you put it on ggplot2:
ggplot() + xlim(c(-1,1)) + ylim(c(-1,1)) +
geom_text(aes(x=0,y=0,label=paste(txt,collapse="\n"))) +
theme_void()
Print OLS regression summary to text file
In order to write out the result
of pandas.stats.api.ols
, use a text file to match the output format, for instance:
from pandas.stats.api import ols
grps = df.groupby(['FID'])
for fid, grp in grps:
result = ols(y=grp.loc[:, 'MEAN'], x=grp.loc[:, ['Accum_Prcp', 'Accum_HDD']])
text_file = open("Output {}.txt".format(fid), "w")
text_file.write(result.summary)
text_file.close()
How to export summary statistics of a regression from R studio to Excel
Let's assume we have model called "mod"
mod <- lm(v1 ~ v2, data= df)
You can use "broom" function.
library(broom)
#create dataframe with results
res_mod <- as.data.frame(tidy(mod))
res_mod2 <- as.data.frame(glance(mod))
#then export as csv
write.csv(res_mod, "res_mod.csv)
write.csv(res_mod2, "res_mod.csv)
