I am new to R so no idea about the code. I have two data frames. One dataframe looks like this.
ID | Disease |
---|---|
GSM239170 | Control |
GSM239323 | Control |
GSM239324 | Control |
GSM239326 | Control |
GSM239328 | AML |
GSM239329 | AML |
GSM239331 | AML |
GSM239332 | Control |
GSM239333 | Control |
And the other dataframe looks like this:
GSM239170 | GSM239323 | GSM239324 | GSM239326 | GSM239328 | GSM239329 | GSM239331 | GSM239332 | GSM239333 |

I want to make a table to include mean_AML, sd_AML (standard deviation), min_AML, max_AML, mean_Control, sd_Control, min_Control, max_Control, and Fold_change (ie, mean_AML – mean_Control) for each gene. It is fine to use built-in functions.
Can't figure out the way how I can do this. Please help.
Thanks.
We could combine pivot_longer
with right_join
and then use summarise
on the group:
library(dplyr)
library(tidyr)
df1 %>%
pivot_longer(
everything(),
names_to = "ID",
values_to = "value"
) %>%
right_join(df, by="ID") %>%
group_by(Disease) %>%
summarise(Min = min(value), Mean = mean(value), Max = max(value), Sd = sd(value)) %>%
ungroup()
Disease Min Mean Max Sd
<chr> <dbl> <dbl> <dbl> <dbl>
1 AML 2.13 4.91 9.53 2.04
2 Control 2.13 4.92 11.4 2.12
It will help to put the second dataframe in long format using pivot_longer()
:
library(tidyr)
newdf <- pivot_longer(df1,
cols = everything(),
names_to = 'ID',
values_to = 'value')
Then merge()
the two dataframes into one:
df.all <- merge(df, newdf, by = 'ID', all = T)
Then you can group_by(gene)
and summarise()
, adding whatever values you need:
library(dplyr)
df.all %>% group_by(gene) %>% summarise(sd = sd(value), min = min(value), max = max(value), mean = mean(value))
Another option with old function tidyr::gather
to have a column df:
library(tidyverse)
df2_spread <- df1 %>%
tidyr::gather(ID, val) %>%
left_join(df, by = 'ID')
df2_spread %>%
group_by(Disease, gene = ID) %>%
summarise(n = n(),
mean = mean(val),
sd = sd(val),
min = min(val),
max = max(val), .groups = "drop")
A tibble: 9 × 7
Disease gene n mean sd min max
<chr> <chr> <int> <dbl> <dbl> <dbl> <dbl>
1 AML GSM239328 16 4.91 2.15 2.13 9.30
2 AML GSM239329 16 4.95 2.13 2.27 9.53
3 AML GSM239331 16 4.88 1.96 2.26 8.29
4 Control GSM239170 16 4.56 1.91 2.20 7.98
5 Control GSM239323 16 5.04 1.98 2.33 8.82
6 Control GSM239324 16 4.93 2.45 2.13 11.4
7 Control GSM239326 16 4.97 2.34 2.18 10.7
8 Control GSM239332 16 4.97 2.16 2.25 9.77
9 Control GSM239333 16 5.01 2.14 2.29 9.77
In any case I'm not able to find a way to calculate Fold_change for each gene since there seems to be only one disease by gene here.
Here are the datas
