I'm doing a study of two types of cancer using TCGA database. I have already used some scripts in R to find the upregulated and downregulated genes of each cancer and the both intersection.

Now I need to calculate de survival rate, and I'll use SPSS software. Then I need to do a table with the individual code, normalized dosage of genes, survival time and death.

But I don't know how I'll obtain this table.

Somebody could help me, please?

Welcome to the site. This might not be the best place to get SPSS help, as the site is dedicated to support Bioconductor R pacakges. In any case it would help if you provide what have you tried: code attempted, pages visited that helped you, ...

Hello, I want to use R packages to create the table that I will use on SPSS. I found this code on Youtube, but there are some things that I didn't understand.

library(DESeq2)
library(TCGAbiolinks)
library(survminer)
library(survival)
library(SummarizedExperiment)
library(tidyverse)


clinical_HNSC <- GDCquery_clinic("TCGA-HNSC")
any(colnames(clinical_HNSC) %in% c("vital_status", "days_to_last_follow_up", "days_to_death"))
which(colnames(clinical_HNSC) %in% c("vital_status", "days_to_last_follow_up", "days_to_death"))
clinical_HNSC[,c(9,43,48)]

table (clinical_HNSC$vital_status)

clinical_HNSC$deceased <- ifelse(clinical_HNSC$vital_status =="Alive",FALSE,TRUE)

clinical_HNSC$overall_survival <- ifelse(clinical_HNSC$vital_status == "Alive",
                                         clinical_HNSC$days_to_last_follow_up,
                                         clinical_HNSC$days_to_death)
write.csv(clinical_HNSC, "tabela.csv", row.names = FALSE)

dds <- dds[keep,]

hnsc_tp53$strata <- ifelse(hnsc_tp53$counts >= median_value, "HIGH", "LOW")

hnsc_tp53$case_id <- gsub('-01.*', '', hnsc_tp53$case_id)
hnsc_tp53 <- merge(hnsc_tp53, clinical_HNSC, by.x = 'case_id', by.y = 'submitter_id')

Edit the question to add the relevant code and specify what do you not understand. Good luck!

I have already used this code to find what genes I will focus in
